How to Easily Fix Cracks by Plastic Welding!

Sometimes a crack in a bumper will be sent to the dumpster real quick, but with the knowledge in this video they can easily be fixed. In this Episode I am using the most basic plastic welder to repair a 6 inch crack in a plastic bumper cover. I have broken down the steps to make it easy for any DIY attempting bumper repair for the first time!

Just wanted to say many thanks. I've been watching your posts for a while now. Had been going to ask how to do plastic repairs as I'm trying to repair a gsxr. The fairings are needing cracks filled and painted. Other issue is the bike had been knocked over in my garage and the petrol tank had an axle stand pierce the tank. What would be the best way to pull the split edges together, I did purchase a two part metal filler to plug the hole in the tank although there is still a crease hence I'm unsure of best way to repair, fill and sand as to get the best finish possible. I'm spraying the bike to match my wifes weekend toy which is an obsidian black 2.5 ltr Subaru Impreza sti. The Subaru J32 obsidian black has an amazing colour and very light sparkle to it. Also I've seen some paints that can supposedly spray the alloy frame. Any tips on painting those. 1507Lachlan on Instagram 😀

I've been in the paint business for 50 years , us old guys can always learn something new ,I really appreciate your show And take care !!🍺🍺

[@nicolajskovby6204]

As long as your willing to learn you never get too old

[@robertlangley258]

It’s always nice when a professional will take the time to show us wannabes how to attempt to do what they can do in their sleep. Thank you very much.. This is an excellent video well narrated and produced.

[@PaintSociety]

Thanks Robert. I read and listen to all the comments and even better videos follow.

[@CBrigante]

Hello greetings from Tijuana Mexico. I own a small paint and body shop and I am very happy to have you share your knowledge with us.

[@thefreedomguyuk]

For those not having the equipment, a zip tie does it equally well. Use a lighter to set fire to, and melt, the zip tie, while holding it above the damage. The drips from the melted zip tie bonds with the plastic, and it gets really strong. With a bit of practising, the result can look like a TIG weld.

[@tomr1107]

thats how i used to apply p-tex ski and snowboard base repair. thanks for the tip!

[@bobweiram6321]

@@tomr1107 You have to make sure it's the same type of plastic or it won't bond.

[@paulrobinson7156]

Cant control temperature of the plastic its dripping on so wont bond together or weld together,have you done the right test to id the plastic that needs fixing ?

[@Marcoosianism]

The damaged plastic must be melted as well to mix with the filler plastic. Drips of burned plastic will not heat the damaged plastic to the correct temperature for melting and will barely stick to but not bond to (or repair) the damaged plastic.

[@vickikgibson9470]

Awesome info as usual, and I enjoyed your detail. No skimping on process, which matters!:) Proper repairs make a world of difference for lasting quality. Some of us are working on those special projects we don't want to pay an arm and leg for, so knowing how to do it right really helps! Thank you!!

[@ryanhawks6600]

DUDE!!! you literally have a video for every repair i need to ever do! .....and always a top notch, detailed tutorial that educates while entertaining. Thank you for all the work you put into this channel brother!! Very much appreciated! - Hawk

[@PaintSociety]

Thanks Ryan!!

[@aztecamechanicalelectrical2103]

I just love the way you explain the process, please keep it up.

[@leoclement3801]

Awesome tutorial my friend. I really like how you take the time to thoroughly explain each step by step.

[@debrac1688]

You are a good instructor. You speak clearly, good pace. Thanks for clarifyin WHY you need aluminum tape. I learned lots and enjoyed it too

[@G58]

I’m going to try this method on my cracked bike plastic parts. Thank you for sharing

[@UtahDarkHorse]

Great repair and super video. I've begun to try repairing plastic (not car bodies), and this is really helpful. Thank you for sharing 🙂

[@GA-tl4iy]

Thank you Brian, you spent a lot of time and finally you did a great job.

[@akemii3594]

Cool..good to know..bought my own first ride on a manual to learn how to drive, had mini accidents that fd my bumper & got it replaced for a couple hundreds..so i appreciate the time you put in this video to show us how we can invest in a tool like what you have shown us so we can diy our cars in welding plastic. Thanks man.

[@MichaelChanslor]

Thank you for the no BS, clear and concise video. This has really helped me out. THANKS!

[@Marijonukas]

after watching this, now I am qualified bumper restorer.

[@ambrosepearce413]

Love this one! I bet the repair gave the panel some strength. I've done this with minimal tools and success. After watching this I feel I could confidently make a proper repair. Your awesome Brian, thank you for sharing your skills with us!

[@PaintSociety]

Thank you. It doesn’t take much after you watch the video, it just takes patience. No real skill needed.

[@jlp5137]

I have a tip for you. If you want to speed the process up a lot you can get one of those little pencil torches and use that along with the flat tip to get things warmer faster. I use them all the time and my crack repair time is 75 percent faster. Obviously, you need to be careful not to get the plastic too hot but you know that. I have repaired hundreds of cracks with a torch and the welder and never had one fail. I also wanted to say that I actually think that my welds with the torch are stronger because I find that the plastic welder just doesn't get the bumper cover hot enough to bond all of the plastic together

[@PaintSociety]

Thanks. Great tip!!

[@keithbau.gardner6080]

This video came at a perfect, thank you , we have to fix my sons bumper , we bought the kit a while ago, i have never fixed one , but you just made that easier for me, once again, great video

Very informative Brian .Great tutorial!

Nice repair. I loved the detail and the way you explained the process 👍

[@kirstenspencer3630]

Fantastic, had no idea how it was done CORRECTLY. Lifetime repair I dare say. Many thanks for sharing.

[@kickzip]

Great instructional video! Being a fabricator welding plastic for years my tip is to use acetone on PP or PE to clean before welding.

[@MarkSexton887]

Once again.thanks for the lesson.having the right tools.for the job,is the key. Brian please stay safe. 🇬🇧

It is key! Stay safe

Thanks for your clear and detailed video. Now I feel comfortable repairing my older BMW’s damaged bumper cover.

[@justinshields4216]

This by far is the best welding kit I've seen!

[@PaintSociety]

It’s pretty good. Simple

[@fongsenlay270]

Hi Brian, I'm from Australia and just want to say great tutorial as its a different way to how i repair plastic. I use a hot air welding gun and heat up both plastics and let them fuse together.

[@jaggass]

I've probably shortened my lifespan after doing some plastic welding but the repairs are nice and solid. It saves throwing them in the bin and didn't cost me anything.

[@debrac1688]

Yeah. I was wondering why you guys aren't wearing masks

[@jaggass]

@@debrac1688 When plastic welding now i either do it outside or with a mask on next to an extractor fan.

[@anthonyu3300]

I love watching these how to videos! For some reason with body work and painting projects I end up throwing something, cussing or messing it up more!😁

[@ze_german2921]

Pretty neat! Always wanted to know how to weld with plastic. What I have been doing is use Fiberglass mesh from screen doors and windows and glues the mesh to the joint with 5min epoxy, then Bondo the front.

[@brianhund8177]

Excellent tutorial on plastic welding, great tips, thank you

[@Nani17659]

I'm trying to start a business in this field and ur video wS much more helpful then instructional videos

used this video to put the mesh on my new hood scoop so I can start to bond the scoop to my hood now so it's functional. thank you!

[@robertbarr8001]

Good, informative video. Many thanks for taking the time.

[@alexxicotli7665]

You are a great teacher, Thanks for all your insight!

[@Order4627]

I weld the crack to parent plastic only and it works every time. The green lids off milk bottles in the uk work well as filler. Yellow 110 volt site plugs also work well as filler if cut into strips. I did a video on how I do it.

good job, i do the same but different,,when i get a bumper that needs to be replaced , i take the no good bumper and i strip the paint off of it and i cut strips of it and save it to melt on a bumper that needs to be fix down the road,i save money ,and i can fix a bumper pretty cheap,,,my heat rod is a 10 dollar rod from princes auto ,,people laughs at it [or at me], i really donnt care because it gets the job done,,and when their 300 dollar heat rod broke,,than they ended up buying a heat rod like mind,,,now whos laughing,,i am enjoying watching your videos, for i am learning something from every video,,,i just wanted to say,,,thank you and your follow workers for shareing,, thank you

Awesome and you’re right. You think smart and taking apart a old bumper is a way to save money!

[@mikez1569]

Very nice job brotha! Thanks for the videos thru these crazy times!! Keep up the great work bro!

[@PaintSociety]

Thanks Mike!!

[@ObNoXiOuS1]

Hi Brian, great video. From my limited experience, drilling a hole in each end of the crack would prevent the crack from expanding further if the area was to be damaged again. This would be done before the sanding usually. 👍

[@jonnyshoestring9368]

That sounds lik a good idea👍👍

[@Cheepchipsable]

That's what they do to stop cracks spreading in glass and engine blocks/cylinder heads.

[@moegizzard5788]

Thank you for that idea about the holes i am going to use that when fix my cracked front bumper..

I use a propane torch, an old screwdriver and black zip ties(for filler rod). Worked on a radiator, interior plastic, broken headlight (the back side of course, not the clear front side). Haven't tried it on a bumper cover yet but I'm sure I'll have to eventually

It went awesome,, bumper looks great , thanks for the video it did help out , keep them coming

Glad you covered plastic bumper repair snd using polyVance equipment as I was curious how it would work out snd the steps besides the how tos on their website.

[@TheCatoLee]

Been doing plastic repair for years also, and just have to be that guy who point something out. . Of course : great video! Liked it a lot! In my experience, preheating the object with a heatgun until you see it becomes just a bit sweaty, (not much tho) will bond better. Plastics bond the best when both sides are “tangible” (hot) The massage after is what really does it. Too much heat can do the opposite favour of what you want, so mess around and make notice.. 220degrees C is a sweetspot. +/- 20 imo... Mostly i use handheld extruders with temp settings.
