I'm building a set of book cases to be installed, kinda built in. Anyhow, I've only ever used clear finishes on my projects, so when the wife said she wants them painted a color, it threw me. I don't know what type of paint to use. I have a gravity feed, compressor type HVLP sprayer that I use for clears. For colors, all I know about is rattle-cans and latex...sad, huh. Don't know whether she wants a clean paint job or that used furniture type finish. Help, please!
