I have no white nitro primer. I am changing my guitar body from a black to vintage white (more creamy than white). Both nitro paint. Can the below white shellac I already have be used between them to get a white surface in order to get a better spray over color for the vintage white? Is this even necessary? My goal is to keep the vintage white as light in shade as I can without the black affecting it.
