I have a 30 gallon compressor I will be using to PC.. I have had it for a few years but only for air tools. Right now all I have is the regulator that came on the tank. The little black filter that came with the hotcoat kit goes on the gun, and at Home Depot the other day I bought a $20 filter made by husky.. will this do the trick or do I need more/different filters, water traps? What do you guys use?
