if you use a high build 2k primer, thats thats got iso's in it, because it has hardner, 2k base coat is just thinners, so is not so bad, then laquer has hardner in it, and same also iso's, 2k solid basecoat, ie plain red/blue etc, that has hardner and iso's, here's a pic of a saxo i painted a couple of weeks ago for a mate, in his dusty shed, with a crappy little 50ltr compressor and a basic spray gun of his, i wouldn't even use for primer, it's done in 2K....
