Ok, i have these tails im working on and i was given this plastic epoxy from my old auto body instructor to use and its worked great and theyve been done for bout a year so i dont remember what i used being i used it all. but now im sanding down the housings and bein the epoxy did take some time to fully cure air pockets have formed and i dont know what to use to fill in the holes.. is there anything at maybe auto zone i can grab just to fill in small holes? im really at a lose of what to use.. any suggestion peeps?

does the silicone get hard? it needs to be something that hardens and is sandable/paintable.. dont want like a rubber feel

here is a pic of what i mean(dont mind the black circles, thats for something else. just notice the holes in the epoxy. i primered it grey so u could actually tell there not just like dips.. there holes)


basically what im looking for a is a filler type stuff.. like body filler is to metal..

still tough to tell, but is what the pic is showing visible when the tail is installed?

maybe some spot puddy would work?

well i would start all over, using fusor or 3m plastic repair material, remember "bondo" does not stick to plastic, or use the same material that the teacher gave ya
even using fusor and puttin 3m over that it will not stick and peel right off, so ya need to use the same material


can i haz bondo

Try bondo or fiberglass filler. You can get those from autozone.

horsepower is the force that determines at what speed you hit the wall, torque is the force that determines how far you take the wall with you after you hit it.

You should NOT use BODY FILLER (Bondo is a name brand) or fiberglass on plastic

This has been addressed before... but to answer your question:

Body filler and fiberglass doesn't' really flex much at all. Plastic on the other hand, flexes much much more. So, If you use something to "fill" or "repair" a plastic that doesn't flex... it''s not going to hold, it will crack/break off.
