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

I have used modeling clay to mold a good part, like the other good tab, then transfer the mold around the broken tab. This makes a perfect replica of the section that is missing…when the epoxy is cured you can just peel away the clay and you have the finished product…
Professional plastic-trim repairers use RF (radio-frequency radiation) to repair trim & grilles, etc., as they can finely focus the beam to weld the plastic just at the breaks. Not having that sort of equipment, I've improvised with a temperature-controlled soldering-iron, adding plastic where needed. In the past I've tried epoxy-glue, but found it just didn't retain its grip to plastics like ABS & PVC when subjected to vibration & extremes of heat.
However, some plastics can be bonded extremely well with the better quality super-glues like 'Hot-Stuff' because it will dissolve & liquefy plastics like acrylic, but I found the cheap super-glues & the 'Original' Hot-Stuff (red label) too runny to work with, & quickly caused white blooming/fogging to form on surrounding surfaces from the vapours given off! Better to use the 'Gap-Filling' (orange label) & 'Ultra Gap-Filling' (green label) Hot Stuff, building it up if necessary, but still a good idea to have the area well ventilated to prevent 'blooming'. I've successfully repaired several cracked tail-light lenses using this method.
For a surface that adhesives won't stick to easily, I usually use baking-paper!
FANTASTIC video!
Baking soda and low viscosity super glue let's you do plastic repairs too.
I also use tinfoil where you used the blue tape to make the form/tray.
Very nice idea, makes me want to repair some plastic clips on my 09 nissan maxima
You can also use light weight balsa wood (think oldschool model airplanes). Its rigid, can be cut, shaped, and drilled easily but it's very porous and will absorb the epoxy very well. Once the wood absorbs the epoxy its incredibly strong and rigid.
Maybe the epoxy here in germany is a little bit different. but almost everytime i made the experience, that it came off the plastic, the moment a little bit of pressure is applied by a screw or while putting it in place.
Someone from the car industry told me, that car plastic is almost impossible to glue, because it is made out of thousand different types of recycled material. its different types of polypropylen xyc, old rags, potatoes (yeah potatoes) and even waste from butchered animals.
i usually get a sheet of abs and cut out a whole new piece. then abs cement the 2 pieces together. yours is probably stronger though.
Excellent and well thought out production!!! I enjoyed watching the process and learned something as well.✨🎆🎇🎈
