Just bought a compressor and a gun and I'm looking for some opinions on setting up my line. I will probably be painting no more than 3-5 guitars or so a year. With that said, to keep moisture and dirt ect..out of my finish, do I have to have an elaborate set up in my line with piping, drains, filter ect.. between my compressor and my gun? Or would I be OK with just a filter/regulator in the line and a filter at the gun? Thanks for any and all help!
