The guys at the paint desk here are the best! They answer questions, you don't have to wait for 20 minutes for someone to talk to you, and get this--they know what they have in stock and how to use it. They aren't open on the weekend, but it's worth taking off work a little early if you can. Also, take note, they have POR-15 products, which I am thankful not to have to buy by mail any longer.
