When finish applying fiberglass, do u shot it wit primer like u do body filler? n then the paint......... ?

Answer 1

you should be able to paint the wood you use if you are on a flat spot or you will be sanding a lot and for any round spots just do what the fiber glass you use recomends for the mix and primer it all and yes bondo will stick to wood but dont use to much or it will crack


i have my own custom stero shop and have done lots of fiber glass work

Answer 2

Your best bet would be to use the fiber sheet base, and add the resin mix to it. This stuff is made for that, and should work out better than using Bondo. With the fiber sheet, and resin, you can build up a box just the way that you want it. How you mount this box is going to be very important to how good you "sound" does sound. If the box is not securely fastened, then it can vibrate. If it does, it may not be a good sound that is added to your music.
