I'm afraid I don't even know the correct terminology! Ive got a two piece body with two other wood strips that run through the body and I"m wondering how to fill any gaps between the sections. I was planning on using grain filler but I'm concerned that it will show if there are any gaps. Will the grain filler end up transparent or will it be visible between the woods. I don't plan on applying any stain. Here's a pic of the body. Thanks Oh, and do I need to use a pore filler if I've used a grain filler?
