I have had my box built for a while, but I have been thinking of changing it a bit, i want to maybe take the carpet off and maybe put a layer of bondo on it I don't know if that would work at all, or do fiberglass on the outside, how would bondo look painted, just wondering, thanks

well, bondo I think wouldnt be the best, just try sanding the surface with 40 grit paper, then a coat of fiberglass resin. But i duno what im talkin bout

Bondo body filler is fiberglass resign with filler so it takes up more volume. I'm not sure what type of filler the used. But for smoothing a surface either one should work.

I think bondo is harder but more brittle than just straight fiberglass resin. I would use fiberglass since your box will flex with heavy bass and could crack bondo.

I would go with fibergalss unless you have the art of mixing Bondo and hardener down to a science and can do it perfectly each and every time. Fiberglass will stand up to the abuse alot better than bondo will too.........

bondo will crack.... that is why systems are made with fiberglass.... Fiberglass is a lot stronger than bondo

there is this stuff called bodo glass for fiberglass, you think that would work at all

squid this is about your bumper what style is it i looks like a 360 modena i love it
