I have read so much that my head hurts and I’m partly confused. Being that I used to be an ASC certified painter and body guy, I got that part downpat. What has me is what is the best route to choose. I bought a re-store full size convection oven for $45 this week. With so many options of powder and types of powder guns to choose from I don’t know which one is the overall best powder type to go with (I don’t mean brand). From a cost perspective, which spray method is the most reasonable? I’m ocd enough to know that I’m gonna be the stand up boolit and spray kind. What is a mid grade spray gun recommendation?
