At this point, my drums have been stripped, de-covered, sanded, and shellac-ed. I'm going to paint them, and probably put a nitrocellulose finish on top of the paint. my concern before painting, however, is the inside of the drums. i'm thinking of just putting a couple coats of shellac on the inside to just give the wood extraneous stability. i'm not sure how the sound will come out though. has anyone done this before? what about stain, or even nitrocellulose [on the inside, that is]?
