Jim, I have a couple of the HF guns too. I also have a nicer SATA. I mainly do spray bomb because it is faster, sometimes cheaper. I realize you don't get the same durability as gun shot paint. The next project for myself will be the 40 and I want it to look nice for many years. That's why I decided I will shoot all of it with a gun. It may a challenge since our winters aren't conducive for painting. Haha
