How To Repair Broken Plastic Car Parts

How To Repair Broken Plastic Car Parts

With how much plastic is in cars, it’s only a matter of time before some plastic breaks in your car. In this video we use epoxy to fix the broken glove box in my R32 for about $10. Ive also been able to fix a few kids toys with the same method. You can also use washers, or even a paperclip to reinforce the repair. #DIYwtihDAP #humblemechanic

    STUPID BEAR ! LOOOK DIRTY !

    Another good way to do this would be plastic welding. Just grab a soldering iron, melt the pieces together a little, then add in (melt) a zip tie and you’re golden. If you really care about the cosmetic result, you can also put a little aluminum tape on the front side and weld from the back!



  3. Peter Diotte on March 21, 2023 at 7:37 pm

    Great video – thank you. I bumped the garage side with my mirror and broke a couple tabs holding the turn signal. New part would be $100, complete assembly $125. I’m going to try your approach to repairing the tabs! Thanks for the info and for showing the glue to use. Plastic adhesion is tricky – good to know the best glue.



  4. YesUCan on March 21, 2023 at 7:37 pm

    Beautiful examples on the repairs, but with so many broken pieces, I’d have gone to a salvage yard, lol. Nice job!



  5. Paul Simon on March 21, 2023 at 7:37 pm

    Try taking an impression of the good tab with plasticine, putty or some moulding clay then push it under the broken side as a mould into which you can add resin with fibres.



  6. Nate Who on March 21, 2023 at 7:38 pm

    New tech here and gosh these things r kicking my butt and gettn to me. Not matter how hard I try I’m doomed lol๐Ÿ˜…๐Ÿ˜…

  8. scorpion netherrealm on March 21, 2023 at 7:42 pm

    Ironic ive got a question regarding the mk4 glove box how can you straighten the part that hits the light switch mine is so crooked it annoys me that the light dont work.



  9. Kobe 19 Corona 19 on March 21, 2023 at 7:44 pm

    My 3g eclipse 2000-2005 needs this the dash is broken everywhere



  10. Anthony Marshall on March 21, 2023 at 7:44 pm

    Some good ideas, but personally, I’d cut the back off flush and use the other one as a template, to make a new one out of plastic or ally.



  11. Pinalloy on March 21, 2023 at 7:44 pm

    this is what i need badly. Thanks so much ๐Ÿ™‚



  12. george colvin on March 21, 2023 at 7:46 pm

    My wife used a similar method to fix a unsightly crack under her sink unfortunately when I stood back up it caused alot of pain and discomfort but to this day she stands by her decision. And I have to give her credit its still holding up



  13. Ru Shodai on March 21, 2023 at 7:46 pm

    Makes me want to go out and fix things.



  14. Alex Game-Autos on March 21, 2023 at 7:46 pm

    Never understood why do you call it a Q tip? Haha is that the real name or somthing I only know them as ear buds๐Ÿ˜‚



  15. Nehpets Rellek on March 21, 2023 at 7:46 pm

    Purdy cool. I have some of this kind-a work to do on a 1998 dodge B-350 van restoration.
    TKS for the knowledge.

    This is one of the most useful videos I’ve ever seen on YouTube. Thanks for showing and explaining so thoroughly, sir!

    To repair a broken turning signal light plastic housing on my 86 Bronco I used the Oatley "All purpose cement" .It basically "welded" the parts together and the repaired housing looks like new…It also works great on repairing the plastic frame around headlights..



  20. Lilia uvu on March 21, 2023 at 7:51 pm

    Great video thank u



  21. mrjameschong on March 21, 2023 at 7:52 pm

    my dear and bearded teacher, if instead of using cardboard and parchment paper to repair the glove box I had used plasticine, surely it would have been better… sincerely commander krazy glue hahahahahahahahahahahahahahaha



  22. Steve L on March 21, 2023 at 7:52 pm

    Cool techniques! Enjoyed watching this episode!



  23. Rhonda Kendrick on March 21, 2023 at 7:55 pm

    thank u for info



  24. Lobster on March 21, 2023 at 7:56 pm

    It cant be mentioned enough how important temperature is for working with epoxy. Ask me how i know. If you work with epoxy in a unheated workshop during the cold seasons it might never go off and you will have the worst day of your life.



  25. Gabriel Pontual on March 21, 2023 at 7:58 pm

    Lol, I have just bought an old Golf MK4 and it amazes me how most of the car interior DIYยดs Iยดm finding are from Golf MK4 owners



  26. YesUCan on March 21, 2023 at 8:00 pm

    14:00 why is there a burn mark on the wax paper?



  27. pugdad on March 21, 2023 at 8:01 pm

    thankyou so much for taking the time to make this video this was a tremendous help!



  28. QuestNoise on March 21, 2023 at 8:02 pm

    Hey, Charles. Wondering if you’ve ever tried an epoxy or plastic weld repair on a MK5 tail light, specifically the clips that hold in the bulb holders. Those clips are under a great deal of tension since they compress the bulb holders against their rubber o-rings. I’ve already ordered a new light because I can’t see any repair being both strong enough and flexible enough to be as good as new. But, I’d still love to try to repair the broken one just to see if it can even be done. Let me know what approach you think would be best. Thanks.



  29. Ian L on March 21, 2023 at 8:03 pm

    @HumbleMechanic – if you like Epoxy you’ll love Plastex ๐Ÿ˜€



  30. Delisa Velez on March 21, 2023 at 8:03 pm

    What type of spicy is it



  31. Jay Bee on March 21, 2023 at 8:05 pm

    that heated paperclip move is big brain



  32. willbedone777 on March 21, 2023 at 8:05 pm

    ๐Ÿ‘



  33. Andrei Grigorev on March 21, 2023 at 8:06 pm

    Pretty sure you should be able to use modelling clay instead of the parchment paper to prevent epoxy flowing where it is not supposed to. Might be easier to work with, too.



  34. ๅดestib on March 21, 2023 at 8:09 pm

    nicely done video man! hats off to you



  35. Markg330 on March 21, 2023 at 8:10 pm

    As an owner of an h2 with some flat out ridiculous prices for plastic pieces I thank you! Haha



  36. F M on March 21, 2023 at 8:15 pm

    I did a lot of plastic repair using super glue with a lot of epoxy reinforcement. I used ordinary plastic wrap to set the flat parts on, not caring if not all of the plastic wrap came off. To my surprise, none of the plastic wrap stuck to the epoxy.



  37. Stephen Gribben on March 21, 2023 at 8:17 pm

    awesome tips and tricks on fixing these breaks. I have an older Toyota tundra that has various cracked pieces and i cannot buy new ones…just not available. Now i feel that I can do this! Thanks man! New sub



  38. Stormman on March 21, 2023 at 8:19 pm

    Excellent video. Thanks for doing this.



  39. Hector Gonzalez on March 21, 2023 at 8:19 pm

    Hey I have a mk4 gti 24v vr6 and wanted to fix my fitment but canโ€™t go lower because of my oil pan being way too close to the ground, is there anything I can do to fix it?



  40. Dale Kundtz on March 21, 2023 at 8:23 pm

    Thanks for great tips for us backyard mechanics on a budget…๐Ÿง”



  41. Steff320i on March 21, 2023 at 8:23 pm

    Aaron Kaufman, is that you?



  42. Tally Beaverman on March 21, 2023 at 8:24 pm

    I was looking for instruction for replacing my door pins. Found 3 that impressed me, so I was going to go with one of those. 2 days later yours showed up as "suggested", and it smoked the rest. Now I will be checking your channel first, before the rest! Good job!



  43. AlexT on March 21, 2023 at 8:26 pm

    Great video. I have to pay more attention to this channel.



  44. Jake2 on March 21, 2023 at 8:27 pm

    Designing and 3d printing plastic tabs and clips to epoxy onto expensive trim is a game changer



  45. Daniel Pintal on March 21, 2023 at 8:27 pm

    Thank you for your clip! Very informative and helpful



  46. HumbleMechanic on March 21, 2023 at 8:27 pm

    I hope this video inspires you guys to have a crack at fixing something before just replacing it. There are almost an infinite number of ways to fix this stuff… What is your favorite?



  47. Flemming Tobiasen on March 21, 2023 at 8:28 pm

    Vers cool repair ๐Ÿ‘๐Ÿป๐Ÿ‘๐Ÿป.. Why just buy a new one?



  48. Hanno Meins on March 21, 2023 at 8:29 pm

    That’s great! Well done – Thank you so much.



  49. Gplus Gplus! on March 21, 2023 at 8:35 pm

    After 26 hours the 5 minute epoxy is still tacky on the repaired section. If I put the panel in the car, next time I try to remove it it will have glued with the backing and rip off the plastic in pieces. ๐Ÿ˜ก



  50. enterprise59 on March 21, 2023 at 8:35 pm

    We have a small hole and crack in our clear instrument panel cover. We can’t take the panel out as we’d have to remove the entire dash cover. Is there a way to fill in that hole with clear stuff?
