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

    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

  2. HumbleMechanic on January 23, 2023 at 3:17 am

    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?

    Needs a glove for that beard

  4. Daniel Pintal on January 23, 2023 at 3:21 am

    Thank you for your clip! Very informative and helpful

    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. 😡

    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.

  7. Hanno Meins on January 23, 2023 at 3:23 am

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

  8. Amy Hoang on January 23, 2023 at 3:24 am

    Nice! Do you think I can use this epoxy to fix the crack line on my refrigerator’s crisper drawer (just a line, not open up yet)?

  9. Jay Bee on January 23, 2023 at 3:27 am

    that heated paperclip move is big brain

    What type of spicy is it

  12. YesUCan on January 23, 2023 at 3:31 am

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

  13. Steff320i on January 23, 2023 at 3:31 am

    Aaron Kaufman, is that you?

  14. Rhonda Kendrick on January 23, 2023 at 3:32 am

    thank u for info

  15. Alex Game-Autos on January 23, 2023 at 3:32 am

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

  16. Anthony Marshall on January 23, 2023 at 3:33 am

    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.

  17. Tony Montana on January 23, 2023 at 3:33 am

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

  20. Flemming Tobiasen on January 23, 2023 at 3:38 am

    Vers cool repair 👍🏻👍🏻.. Why just buy a new one?

  21. CrystalKids on January 23, 2023 at 3:42 am

    That was awesome… Thank you thank you!

    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.

  25. enterprise59 on January 23, 2023 at 3:47 am

    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?

  26. pugdad on January 23, 2023 at 3:49 am

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

  27. AlexT on January 23, 2023 at 3:50 am

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

  28. Hector Gonzalez on January 23, 2023 at 3:51 am

    Hey I have a mk4 gti 24v vr6 and wanted to fix my fitment but can’t go lower because of my oil pan being way too close to the ground, is there anything I can do to fix it?

  29. Kobe 19 Corona 19 on January 23, 2023 at 3:51 am

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

  30. Solar Flare on January 23, 2023 at 3:51 am

    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..

  31. Paul Simon on January 23, 2023 at 3:53 am

    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.

  32. Jennifer Hofmann on January 23, 2023 at 3:54 am

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

  33. Jake2 on January 23, 2023 at 3:58 am

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

  34. Tally Beaverman on January 23, 2023 at 3:58 am

    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!

  35. Andrei Grigorev on January 23, 2023 at 3:59 am

    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.

  36. Gabriel Pontual on January 23, 2023 at 4:00 am

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

  37. Achmed med Kniven on January 23, 2023 at 4:01 am

    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!

  38. Gianni Lorusso on January 23, 2023 at 4:01 am

    Bravo complimenti

  39. Pinalloy on January 23, 2023 at 4:03 am

    this is what i need badly. Thanks so much 🙂

  40. George Everett on January 23, 2023 at 4:04 am

    Excellent video ! Very good job !

  41. Stephen Gribben on January 23, 2023 at 4:06 am

    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

  42. Ru Shodai on January 23, 2023 at 4:06 am

    Makes me want to go out and fix things.

  43. Ian L on January 23, 2023 at 4:07 am

    @HumbleMechanic – if you like Epoxy you’ll love Plastex 😀

  44. Efrem Williams on January 23, 2023 at 4:08 am

    When I bought my B5 Passat, the glove box door was in the back seat. The secure tabs were broken. I used some JB plastic weld and cardboard box to form new latches for a new box. After a couple days of curing and shaping, I now have an actual glovebox.

  45. Lobster on January 23, 2023 at 4:10 am

    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.

  46. Lilia uvu on January 23, 2023 at 4:11 am

    Great video thank u

  47. Nate Who on January 23, 2023 at 4:11 am

  48. Steve L on January 23, 2023 at 4:12 am

    Cool techniques! Enjoyed watching this episode!

  49. george colvin on January 23, 2023 at 4:13 am

    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

  50. 吴estib on January 23, 2023 at 4:14 am
