Hi, folks, first post here. Love the course, videos and how tos. Been flipping between redoing my '54 Belair interior and my latest mistress, '69 Deuce and a quarter drop top. Just started redoing window weather-stripping and door panels. Plastic arm rests have lots of cracking in them. I seriously doubt I'd be able to find replacements. What glue would be recommended to repair the cracks? There's some large ones where I could probably fit a splice behind the repair, but some smaller ones that I would have to rely solely on the glue. Thanks. BTW, this would me a mostly cosmetic repair as there are heavier framing pieces that hold everything together.

Probably better ways to do it but I use epoxy pretty much the same as sold for fiberglass . I grind out the breaks to form a v , pull everything togather with clamp and tape up the back side with masking tape and dribble the epoxy into the groove being careful to only apply where you can keep level I t gets to be a long process some times . You can reinforce with small pieces of aluminum bent to fit in corners and such Use wax paper between your joint and anything you don't want it to stick too Make sure the epoxy is waterproof because some are not or didn't use to be I am building a 63 Dodge dart convertible for my wife and am using a Cadillac CTS dash , console and shifter I had to cut some out because it was to wide so I cut across right hand side of dash through glove compartment I'm ready to do it over again . The dash I use had been beet up by tree breaking windshield Have a nice pattern to start over again Still have little pieces to make to make it fit to door the way I want Just keep clean ,grooved out and sanded so it stick good and sand smooth after setting good and it can also be done on back side for more strength

I like 3m DP100. Easy to use gun and disposable mixing tips. Little mess and works on just about anything. https://amzn.to/2DLyv95


I bet @Bondo497 has some good suggestions for this as well.

@John I would recommend the same as you. There are so many types of plastics out there that really there is no one product that fits all types best but a general purpose rigid plastic repair compound should work well for that type of repair @JoeTheRoofer is trying to accomplish.
