I plan to use my HVLP sprayer for the first time on a project that is more for practice than for show-and-tell. I picked up a can of Minwax Polyshades at HD but the directions do not include how to spray this product. I have searched this forum and have found others who have sprayed Polyshades with good results. My question is this: Should I thin it before spraying, and if so with what and how much? My spray area is about 70 degrees and 16% humidity. Thanks.
