So, I've been wanting to build a bass for at least 10 years. I've had so many false starts that I finally just decided that I need to do something. So, I'm looking at the cheap kits over at Guitar Fetish and just doing a finish and assemble for my first project. My question is what's a good, durable finish to put on poplar since it's a fairly soft wood? I'm wanting to do an opaque blue with a clear coat over it. It seems that polyurethane is a pretty hard finish and would protect the soft poplar. I was looking at doing a rattle can finish but can't seem to find colored polyurethane. I also I have access to a HVLP spray system since my father-in-law does aircraft maintenance on the side and uses one to paint aircraft from time to time. Would it be worth the trouble of buying a base and mixing color in or should I try to keep it as simple as possible for my first project? For the neck, I want to try to keep it a flat/satin finish. I've never liked the feel of a glossy neck. Is it best just to use something like satin polyurethane for that or is that more a sanding technique?
