Okay man, here's my input i tried spraying some finishes on a project strat guitar with spray paint and rub on wood finishes. The wood finishes turned out better and the spray paint took FOREVER to dry completely... it can take up to weeks for spray paint to settle in completely on wood. So if you can check out stew-mac i think they got some rub on color finishes that would do good for you, then again im a noob too so my info might not be the best to listen to
