if you are going to spray polyester paints, you really have to make the commitment to it....you cant just go out and buy a wagner-causfield gun and go....you got to spend the cash for a good gun, invest in a lot of acetone, have a real spray booth, full body armor and mask.....wherever you spray this will smell forever like polyester, so a stand alone shop is best.....BUT, when you get set up and get the hang of spraying something so thick, its easy as pie and fast..........basically you just bang on some polyester sanding sealer, sands up like glass, paint and clear....3 days
