I want to learn about spray systems and I want to purchase some equipment. I am beginning to learn that I need two systems. One for modeling and one for house painting. I really like the idea of having a pressurized air tank in the shop. I own a Paasche compresser and gun. I see online that Paasche sells a small tank. Will be looking into that. I not sure of the Paasche upper limit yet. I know Paasche is designed for teeny tiny stuff and my gun produces an extremely fine spray. I am also thinking of looking into a system a little larger than a Paasche. I am not sure I am sold on airless for the home painting. Lots of negative reviews online.
