i made an encloser out of wood but i did not finish the top of it with wood, i threw down 3 layors of fiberglass. is this enough? 5-7 layors is usuley recomended for complete fiberglass box, but since this is only the top is 3 enough? or should i add more?.
Sean, Are you using the fiberglass resin with the cloth? or just the resin.
