Ramos, I use an iwata hp-c+, and eclipse hp-bcs. All paint that I use is house of kolor (distributer in town) along with my primers and clears. To be honest I have never tried auto air. I have heard both good and bad things, but as long as I am set up to spray uros I will probably continue to. The one thing that I am not too keen on auto air is having to heat set every layer to ensure it sticks. Heard way too many problems with people not doing this and having problems. Paint however seems to be a good quality that can achieve great results. I am sure I will give in someday and try it out to see what the fuss is all about:crazy:
