Hi All, Art Mars here, I've been painting since I was 14, which is 40+ years. I've lived in Oklahoma, Kansas, and California, and have used similar painting methods in all three states for most applications. I found this site as I googled 'primers' hoping to get a leg up on wallpaper removal post priming, as I don't have a lot of experience in that. (As i, best primer to use after wallpaper abd before paint) Being that I was originally trained at a time when water based paints were new, I have learned a lot over the years, have used probably most brands of paint, and some that are now extinct. My field of expertise has been quality hand painting, texture matching, and quick, effecient hole repair; but I also have a knack for research and development. I make my own stains for furniture mods, repair, and new product. I don't know it all, but I know what has worked well in my many years of product use.
