my bass is leaking

did you use fiberglass matt on there? and if you get a grinder you can grind it off or cut it with a utility knife, what you should of done is routed your edges so there is a about a 1/4th inch chunk cut out of the corner of the wood, staple the fleese to there, that way when you start doing finishing work you do not half to worry about it.hmmm.... was that the right wire?

At this stage I am guessing it is hard as hell, so get a gringer and and give it hell. Good luck.

Again I go back to tiger hair, inside your box box removing the back of the box cutting it or just unscrew it, fill all areas where the glass meets the cloth, that will fill in the areas that cause air bubbles, whiile the tiger hair is still wet push a garbage bag on it to smooth it out, after it dries coat it with resin, Now for the rest, I like to do the fiberglassing on the inside, otherwise you lose the shape that you already designed. Now I know alot of people say that doing the outside is better but trust me this works good. I am assuming that you have desided to remove the back and procced with the tiger hair, after the resin dries up you may need to gring some of the stuff down to get a nice smooth starting point for glass. go ahead and lay out your glass you can do 3-4 coats at a time if you want, your looking for about 1/2" to 5/8" thick depending on curves and design. Be sure not to mix the resin to hot and do not over saturate the matting, the finished material is only as strong as the fiberglass will let it be, to much resin will become weak and maybe crack. Okay, lets say you done with the fiberglass on the inside, you've covered all areas, now your ready for body work. You can send it out to a shop and tell em what your looking for or you can diy. Start by sanding down the now hardened cloth with a die grinder and some 80 grit, 36 is to rough and the rest is to wimpie, 1st grind all the excess fabric on the out side of the wood exposing the tiger hair underneath if necassary. Now gring over the entire thing to get the majority of the high spots out, what you have left will look like a real bad case of orange peel or worse. wipe that all down with thinner, and proceed to body filler skim coats and your on your way, good luck let me know if this helped
