I've ordered a Swamp Ash body from Warmoth for my P bass project. Any advice on finishing the raw wood? I'm trying to decide between going with Lake Placid Blue Nitrocellulose aerasol spray laquer from Guitar Reranch or going with the natural finish. If I were to leave it natural, is it necessary to use the nitrocellulose clear laquer or is polyurethane OK? What about the wood finish products found in the local hardware store. Things like Minwax stain and seal products. Why use nitrocellulose finish?
