My powder coating setup is a Royal Coats RC2 gun, and a cheap pop-up tent with a filter pocket and a box fan on the back to pull overspray through it. I printed an adapter ring so the gun can use cheap cups instead of the single expensive one it came with. Parts get baked to cure in my kiln after coating.
