Since a lot of this is kinda new to me. Are you referring to a HVLP type of compressor driven gun? If you are based on my 6+ cfm at 40psi compressor I am about 60% of 10 cfm needed for most of the guns I have seen offering HVLP. While painiting that seems like quite a bit of "catch up" time. Your experience seems to indicate it's doable.
I have not hit the purchase button yet but the slightly smaller spray pattern of a LVLP seems a resonable tradeoff. I am open to suggestions and common sense real world experience though and just want the most efficient solution.
