Here's how to repair a crack in a plastic bumper.
Cracked bumpers are common on many vehicles that frequent shopping malls drive on rural roads. Often times a replacement is not warranted due to high cost or low quality replacements.
This video demonstrates how you can fix your cracked bumper by yourself at home, with supplies you can get from any auto-parts store.
First, a V-groove is grinded into the back of the crack to increase the surface area for the epoxy adhesion. The crack is then sanded and cleaned.
The top of the crack was secured with a clamp and the front of the crack was held together with tape. JB-Weld Plastic Bonder was then used to fill in the crack from behind. Drywall tape was used as a reinforcement and the setup was allowed to cure overnight.
After the 2-part epoxy is dried, it will be rock hard. From the front, the crack should now be much less visible if it was aligned properly.
Sand the front of the bumper around the damaged area. Use plastic auto-body filler to fill in the cracks, and progressively sand the filler off before applying primer.
Use some rubbing alcohol, paint thinner or acetone to clean the surface before applying primer. The primer was then wetsanded before paint was applied.
The paint was ordered in a spray can from CarQuest and mixed according to the paint code. The color match is very close, just slightly darker due to the 12 year old oxidized paint, and there is a decent pearl that shines back in the sunlight.
Two thin layers are applied then allowed to dry for a few hours before handling. The bumper can then be replaced on the vehicle and fasteners reattached. Wait a few days for the paint to fully cure before applying polish and wax.
Now stand back and enjoy your repaired bumper. The whole process shouldn't take more than a day if you factor in drying time.
This video is an excellent tutorial to follow:

Exactly not to fast not to slow only the necessary info.
Totally agree with you. This guide is precise and articulate, hands down.
I'm a professional in bumper repair and I have to say; great job! For bare-bone materials and tools, you did a phenomenal job my friend. You would give most body shop technicians a run for their money! Left ya a like
+cholzbaugh Thanks for the feedback. For what I spent it turned out good. If I had used the correct plastic filler to smoothen the surface crack it would have been perfect.
kzhead.info/sun/nbmqo6x5n2enjXA/bejne.html
@@speedkar99 what would be the right the correct plastic filler
@@speedkar99 what plastic filler are you speaking of???
@@speedkar99 Hopefully he answers Jose & Ryan soon.
beautiful video. You go straight to business, no cheap talk, just exacly what is important to know. Thank you so much for sharing your knowledge.
That's my style
Yep, on many other channels this would be 20 to 30 minutes long. Ain't got time for that.
i guess he dont need clear coat after XD and buffing out is extra too LMAO
@@speedkar99 Great job. Time efficient and informative.
How much would this cost from a mechanic?
Nice job and an especially nice piece of editing... so we can see the entire repair process in a very short and compact video. I wish everyone edited like this!
+Erik Larsen thanks, short and to the point is how videos should be. Glad you enjoyed it.
yes thanks for not making a 20 minute video that drones on. one question. should i apply a clear coat over the whole bumper to try and make everything look consistent and feather in the repaint?
ya.. i was going to say something similar. Nice, quick, straight to the point, and detailed the same time.. good job. I can't even see the crack on this bumper.
Yeah, i hate it when people draw out a video especially on a big job so it's hard to follow along to

That silver metallic paint is very very hard to match. Make sure to feather it out onto the undamaged area. Shake the cans constantly to move the metal chips around in it.
Wow. I know I say this every time I see one of your videos, but, I wish I could put into words how unbelievably brilliant your videos are, but I can't! Literally no-one else comes close to the way you communicate complex subjects in such a clear, simple, interesting and easy to understand way. You are a genius at this, seriously. Thank you.
kzhead.info/sun/nbmqo6x5n2enjXA/bejne.html
been into cars since I got my first car and I felt so accomplished after successfully changing my low beams after it went out. i get so excited watching these diy vids for quick and easy repairs and mods such as window/taillight tinting and wrapping and being able to know that I'll be able to do these small things for myself.
+Julie Nalay Great
You just gave me hope in being able to fix my own bumper! My husband and I can't afford to get it professionally repaired, but this is a fantastic step-by-step that feels doable! Thank you so much for the clear instructions and list of materials. I hope you're doing well and staying healthy!
How did it go
Perzactly! ANYONE can repair plastic bumper covers! The MOST difficult part is getting the thing off your car... and then back on! Go for it!
2023 here. Sir you are the Standard. Thank you. Made repairs using your techniques. Thank you.
It came out great! Thank you for posting this -- I will definitely use this as a reference when I repair my cracked bumper.
+Sierra Dantzler thanks I'm glad you found it helpful
ian trofimov with 40 grit sandpaper?
Evil D / Yes. The procedure at this first step is to roughen it. In those rough scratches the epoxy "gets, grabs and keeps".
great result. Can get smoother results if you use spot putty before you prime. Also the sanding should have started with 80 grit for the bondo to stick the best. Still worked i see but we shouldnt jump from 80 to 320, but go from 80- 180-320- 400 This ensures the 80 is erased by 180, and 180 erased by 320, and the paint sticks to 400 just fine. otherwise it was still good. I'd recommend fiberglass sheets since they are like 3$ from walmart. And also epoxy gorilla glue @ 5$ Still not hating on your video bro!
Yea where’s your video
The more knowledge the better, thanks for the advice.... fuck these haters.
Had to screen shot your sanding procedure. Thx a million
One word "cost" on how much the customer is willing to pay.
He didnt use clear coat at the end.. was it because it wasn't necessary?
Perfect. You said it all without dragging it out sooooo long like others do. Great vid
THis was such a good video I HAD to come like and comment! Clear speech, good demo, straight to the point, no excessive talking, no crazy intro, exactly what you need to know but nothing less, and great end result! I have a line shaped crack in my bumper that hasn't cracked all the way open to an edge, but is growing over time. I think I'm gonna try this.
This video is straight to the point and very useful. no music , no slow instructions, and it’s flush Thanks !!
Good video, I have this same car in a different color and I just cracked my bumper today in the same spot....smh. Going to do this tomorrow. Thanks!
+MercySaidSo yea ive seen a few accords cracked below the headlight seems like a weak spot on these
WOW what a great job you sir are a pro I am subscribing to your channel not only because you are a pro but also because your videos sir are refreshing, no crazy music, no endless talking about everything, and last but not the least you show your job from start to finish. I wish all these KZhead channels learn from you that a quite video and straight to the point is all what the viewers want. Greetings from Canada
+james mouk Hello my fellow Canadian, I'm glad you appreciate my work here. Making concise videos are what we all need...no need for the extra talk.
Very well said sir and that is way I've subscribed to your channel straight to the point. And thank you for such a great job my fellow Canadian.
Very best video I've seen in fixing a crack in a bumper. Simple, direct and helps you believe, "yeah, I can do that!"
No music nothing fancy just straight to the point, thank you for keeping it professional!!
I love how short the video it is, it gets to the point, and now I’m confident I can do it to my own bumper, of course you have more skill. But I got motivation now!
+Soggy Car I'm sure you can do it! The worse that can happen is your just left with the same crack in the bumper you started with... Just make sure to use the right plastic filler and not Bondo like I did.
Excellent job on the prep fitting the pieces together. So many people fail at using products like this because they don't prep the joining pieces correctly.
+Bank It Thanks. My only improvement would be the plastic filler
I fixed my bumper using construction adhesive, then the Bondo fiberglass repair to fill in the small cracks and holes that were left. Finally put the Bondo finishing filler over everything. It goes on smoother than the fiber glass and you can sand it almost to a high sheen with 1500 grit sandpaper. I then spray painted it and lightly sanded with 2000 grit after first coat and put a very light second coat after that. Finished it all with two quick coats of clear coat and used 3000 grit between coats. Very much a novice at autobody repair and completely winged it, but it came out looking perfect. Especial considering it was a pretty extensive crack. Has been holding strong for just about two years now.
Awesome
Thank you. So many you tube videos get filled with "fluff". This was direct, and succinct! Just what I needed to fix my bumper. Thanks!
Really good video. Short, sweet and to the point.
That was a good, professional, fast job. You guys are the bomb. God Bless you'll for bringing us these videos which otherwise would cost a fortune in these shops. Thanks
+linda ward thanks. I wouldn't call it professional though haha
Thanks for the clear instructions. I will be performing this repair very soon. I plan to clear coat the paint as well.

+jaros s thank you! Short and sweet is how it should be
I did this to my bumper and the results came out great. Thank you!
How’s it holding up?
@@nathancowart not the most sturdy. Lasted a month or so before it split. If i did street only driving im sure it would have lasted years. Lots of beating and banging
Excellent work, perfect pace and editing. Thanks!
You are welcome
I really appreciate your detail, but your videos don't drag out for 20 unnecessary minutes. They're short, sweet, and complete. Thanks for another great video.
Very detailed, yet succinct! After searching youtube for awhile for plastic repair, this video shows the best solution in my opinion. I really dig the dry wall tape for extra adhesion surface. I bought a used Worx snowblower that has a lot of cracks in its plastic body. Looking forward to fixing it, now! Thanks, and great vid!
+Matt Stearns Thanks! All the best on your repair. My only suggestion would be to Make sure you get the correct plastic body filler, otherwise there will be a fine crack where the two parts join. Bondo doesn't adhere well to plastic.
speedkar99 what epoxy should we use then if not that JB Weld bondo?? I got a Nissan Altima SE-R I need to repair my front number cover myself I got a few cracks and a hole I need fixed
Looks good dude compare to what it looked like before good job
Yes at least half decent.
I almost give up. Then this give me hope.
Wow you are a magician by making that crack disappear! Excellent effort in the bumper as well as creating/editing the video. Thanks for sharing and I'll follow your steps as I have a few cracks to fill. Keep up the fantastic work!
Wow! What a great job man! Easy explanation and straight through! Thank you! I will be using your technique on a friends car!

Repairing my 05 Scion Xb and the front bumper needs some work since my brother had a fender bender. There are few cracks held on by zipties but I want to repair the cracks and restore the paint. This really is helpful and will be put into good use
In a few days, I'll try this excellent repair tutorial. I'll let you know how it went.
+Bruce Gibbins how did it go?
Thank you for your response. There have been a couple of delays while my car was in the shop to fix a no start problem I couldn't fathom and I'm waiting on the mail order delivery of the JB Weld that so impressed me. The car is a 1997 Nissan March and the crack is in the front bumper I caused when towing without a towing eye - silly boy, eh.
Bruce Gibbins how it go?
Bruce Gibbins rip
Bruce Gibbins iiiiii
video done correctly. thank you for not babbling on about unhelpful nonsense. straight to the point and totally worth the time to watch.
Great video brother! It's really incredible what you can do with epoxies elbow grease! We just did a how to on a fiberglass bumper with similar techniques. Thanks for sharing your experience and keep em coming!
Thanks
Wow this is amazing!
+Sulihack thanks
Thank you very much for this clear instruction. I order a body kit from ebay but the packaging was bad the body kit ended up being broken.
+jin5632 oh wow, that sucks. All the best on your repair.
You needed a repair kit for the body kit haha
Beautiful work brother. Very educational and straight to the point.
Most channels would have made this into a 30 minute video. Thank you so much for not doing that. It's to the point but still has all the information and demonstrations. Awesome.
Glad you appreciate my video style
Good video, but from my experience, the Bondo can initially be leveled with careful use of a spatula, eliminating the need for extensive sanding, and leaving as much of the original surface intact as possible.
How much it costs?
Didn't skip a step in explaining, thanks.
+xXWOND3RBR3ADXx thanks, short and to the point is how it should be
After water a trillion trillion videos.. I chose this one to follow step by step. My bumper was completely in two pieces and so far it’s coming along well.. I’m currently waiting for it to dry so I can sand and pain it. Thanks so much
Excellent video from a lady who has had the same bumper repaired by a repair shop twice. The car is old now, so I refused, invest the money. The car just sits too low to the ground. A simple pothole, or a parking lot stopper is enough to cause a headache.
Props on the editing. Thanks!
You are welcome
My car bumper is like this, let me go buy some staff when I'm done I will come back here with a reply. This seems so easy. Thanks
How did it go?

Great DIY tutorial! My WRX needs a little love on the from bumper, and will be using this video! Thanks again.
+stipple21 thanks glad it helped
Did you do this on yours how was the paint match?
Great video,,,simple straight forward and keeping the cost down. Very helpful. One of the best videos I’ve ever seen. Thanks.
Glad you enjoyed it
Wow you did a great job! The one thing I would add is a small whole at the end of the crack to ensure it doesn't try to grown in the future.
Good tip! Thanks
What do you mean by that? Like drill a hole? If so what size? & should it be filled with bondo or that jbweld?
Alex Polishchuk I wish he replied back
Lysess Lathro right? Lol
You missed to do the most important thing: a hole at crack end to avoid It to expand!
Yes good tip!
can you better explain that one? thank you!
Matt Bolt drilling a small hole at the end of the crack helps from keeping the cracked area to keep cracking due to tension.
Million dollar suggestion
From an engineering perspective, sharp edges are stress concentrations since it's a function of the inverse radius. At the edge of a crack the radius is zero which means stress approaches Infiniti. When you drill a hole you effectively made the crack's radius the same as the radius as the drill bit, which is far greater than the almost zero radius of the crack. Therefore the stresses in that region are a finite amount, and the bumper crack is less likely to propagate.
Dude this videos great. You’re straight to the point, show the whole process, and you saved me like $90. Thank you Keep up the good work
Thanks. Altbough On some common vehicles like this Accord a $50 junkyard bumper is an easier option
Nice video. Parking brick ripped the bottom of my bumper cover to shreds... for a 160k mile vehicle this level of job will certainly work just fine
Awesome vid man... thanks for sharing. What kind of primer and spray paint do you use btw?
+Anthony Apelu Thanks, the paint was mixed at carquest. The primer is regular all purpose spray primer from a hardware store.
Wow, I need to do this for my Honda Accord as well. Where can you buy touch up paint that will match the manufacturer's? My Honda is silver.
I got mine color mixed in a spray can from CarQuest
your videos are always so great man I'm actually repairing my front bumper on my Civic! love the results on this accord's bumper
Awesome
SUBD ! thank you so much for this video. My car slid backwards into a very sturdy hedge. Smashed tail light and split the bumper plastics. It looked terrible and I was worried as to the cost but , your video showed what to do. Great tutorial dude... Even the respray !
Thanks this is what i shall be doing after hitting a kerb.I shall use fibreglass on the inside where it can't be seen.Thanks for a great video.
+Marc Law I'm glad you found it helpful, post up your results when your all done.
You’re a great help. Appreciate the quality of the work, and quickness of the edits, so that we can spend more time applying the knowledge.
Thanks!
Very nice job and good video. I guess with the exception of using bondo, with something that flex's more as a substitute, this is a great guide. I have to do several bumper cover repairs in the week ahead, so good to see this demonstration.
Thanks for the video me and my husband saved a lot of money repairing our bumper
You should drill the end of the crack to keep it from spreading while your working with it.
+Keith lemon that's a good idea
@@fellaflips3906 look at the end of the crack, drill a hole literally at the end of the crack, helps relieve stress and stops it from expanding.
FANTASTIC
This is the best DIY video I have ever seen, right to the point, thank you!
Thanks!
Don’t know if you’ll see this comment or not but man I really appreciate your video. I have a bumper cover to repair and now I know how thank you for your time and your work on the video.
Perfect men 👍👍👍👍
Thanks a ton , better than buying a new bumper 👌
True. Especially for an older car when it's not worth it
The best video ever on how to fix a plastic crack, especially on a bumper.
Glad it helped
Very nice sanding part the main part for finishing you did good job with patience and pin point video
If there is parts left over, it just means you made it better ;)
+Adrian Junermark eriksson Haha :)
Weight reduction FTW!
Left over parts = increased efficiency
Well I can't say it's the way a professional would do it but the results are excellent
Well its the way you can do it at home! A professional would probably replace the bumper, since they're fairly cheap.
speedkar99 I guess you're right about that. There is a liquid two part plastic. Just like the JB weld. You put it on a piece of plastic like a sandwich bag. Mix it and push it against the bumper. Spread it like bondo. It becomes the bumper. Flip the bumper over when the plastic is hard grind out the crack and fill it with the same plastic. That actually makes the hold mend. Great job!! Show people your work and I am sure you could make some bucks,
speedkar99 Pros repair them too!
speedkar99 One thing would do before painting I would spray on some plastic primer adhesive. It makes the primer and paint stick better and be a little more flexible. You guys are cool. Keep it up.
+Thomas D Harrell Good tip, thanks
you just saved me so much money i am confident i can repair my car myself now Thank you!
no cheap talk, no PPE - not even gloves. This dude is a true BASS 👍 thanks for the great video
kzhead.info/sun/nbmqo6x5n2enjXA/bejne.html
to stop the crack splitting further you should of drilled a small hole the end of the crack
+Wombleton Caravan Park good tip
Then fill it? Or how?
dunno ..guess a circle (hole) ends the direction of the split?
it applies to welding but as far as plastic goes i dont believe it applies but i could be wrong
Yes that's exactly how it works, it ends the split completely.
🤓 thx, how did u get a spray can with oem matching paint?
Carquest
@@speedkar99 🤠🐎 cool, i didnt know u can buy those cans, thx for the video and info buddy 😇
Awesome video. Thank you kindly. Cheers from Aotearoa NZ.
now that is awesome! quick fast and to the point! Looks very impressive
Great job you have inspired me to fix my own bumper lol
Hope it works out
why didnt you use the jb weld plastic epoxy for the front of the crack? that is the first time i have seen someone wetsand with dry sand paper, ha.
+JOEGGGJOE JB weld will dry hard and is harder to sand off the front. Filling it between and behind the crack was sufficient enough.
He used regular 400grit sandpaper, not wet sand paper... then he did actually wet it, but it didnt change the look of the paper. Look again.
If you are a beginner, I recommend using touchup instead of painting. Unless you have a mask and good ventilated area. Don't breathe in paint fumes. I did mine and I should have just used touchup. U have to use duck tape and be really good at aligning the crack otherwise. I didn't do a good job so I just replaced the back bumper cover.
Good idea. Especially for a cheap car like this
Thanks for posting.
Hi it's not a ideal bumper repair. If you use epoxy on thermo plastic make the surface really rough almost hairy then oxidate the hairy surface with heat quickly with a flame torch for example that will increase the bond a lot. The epoxy is much harder then the bumper material. So the to different plastic don't cooperate well. There is another very easy way to repair a bumper that I prefer. Fix the bumper like you did and use a solder iron to melt the bumper together from the inside. If a small piece of bumper material is missing you can use a part from another bumper as a plastic welding rod or to increase the welding joint if needed. I saved a fortune on repairing bumpers like this and the bumpers was broken up till 4 pieces.
Good tip thanks
Niklas Hultkrantz Could you make a video of your procedure?
A week ago I did a repair like that. My panel beater repaired the plastic running footstep cover of a new Mercedes same way. I cant remember the model no of the Mercedes but equwalent of BMW x6

9/10 video the only suggestion I have is lower the sound when you fired up the dremel. Solid repair and easy to follow steps. Left ya a like.
Quality content and perfect execution of the steps. People who critize how you used epoxy instead of welding the plastic are ignorant. The stress that a good epoxy can take will easily surpass the plastic they use in car parts. Thanks for educating us, the fiberglass was a good tip
+gabe st angel thanks for the feedback and appreciation
👏👏👏👏👏
I recently got into accident.. The front bumper was damaged.. Maybe it could be repaired if i had seen your vid.. But i changed to a cheaper bumper..
Looks good and excellent video on the crack bonding. Only one item in that JB Weld Plastic Bonder is not an epoxy adhesive but a two-part, urethane adhesive system. Thanks for all your efforts.
Thanks for the tip.
Most materials you mentioned are all nail supplies I have Thank God. 😭 I never could of imagined I’m about to repairing bumpers and nails 😂
"Great Video" "Short and Great Communication.!"
Thanks very much
Just a few question, what type of primer should I use since it is a plastic bumper and not metal? Also, same goes for body filler, what is the best filler for plastic in this case the bumper? I heard regular bondo used on metal areas do not adhere in plastic parts really well and can crack. Can you let me know name of primer you recommend and name of body filler I would highly appreciate it. thanks!
You need a plastic filler. Not sure what to say on the primer, but something flexible.
Well i know I need a plastic filler. But that’s what I asked what is best plastic filler to use since I’m not familiar with plastic only metal
Hi there is a special plastic primer for plastic bumpers. The bumper can also be wiped with a strong solvent to make the paint stick better I think acetone maybe chloroform will work
Keep you breath if you use chloroform. It's pretty strong or use a mask.
Joss 9 stuff from an Autobody supply that costs as much as a perfect brand new cover by the time you get all your supplies. An OEM subaru cover costs $220 retail thats it man. It good paint work that costs serious money. Fuck this shit $50 repair 🖕🏻🖕🏻
