Should i use a sealer over urethane primer before painting? I've been told BC/CC is best for painting, person at paint shop said urethane "was just about as good". Any thoughts on which paint to use, is one any easier or more forgiving for a beginner to spray? I'm thinking of spraying a pearl or metallic, (probably white with a blue metallic in it), paint shop said you sometimes end up with a yellow effect, (haze ?), using pearl/metallic, is this true, should i stay away from this type of paint. Brand i will be using is Nason. Sorry so many questions but i'm getting ready to paint and want to make sure i get right material.
