One of my best investments for my shop is this Titan Flex spray gun. It was expensive but I was using about ten rattle cans a week. It has a turbine in the handle the head and cup removes and I have multiple ones for different colors. I keep one for clear, black, red and white. I use Sherwin Williams pre catalyzed lacquer. It cost me $26 a gallon. The best thing about the system is that I don't clean it up..........add new product when the cup is empty.
