Paint stores are a lot like parts stores. Some of them the counter people are only there to sell stuff. Other ones they know what they're talking about. There are good paint stores around where the staff are trained by the manufacturers and know there stuff. The one store here will give you recommendations based on what you're trying to do and will tell you if your ideas will work or you should be doing something different. They sell pretty much everything from the paint right down to sand paper, paint guns and wax, even compressors and paint booths. It's always interesting to see what they have on their shelves.
