I'm trying to figure out what it would take to spray "Rust Bullet" (kinda like POR-15, but hopefully better) instead of brushing. I really know nothing about spray guns. I have an air compressor, what should I look at for spraying on stuff that's kind of thick and probably more toxic than normal paint? I'd like it to go on as thick as possible too. I've heard the following terms, and I barely know what they mean: - Conventional sprayer (attach to your compressor, sucks up with a straw? Probably makes the most clouds of atomized paint?) - Gravity feed (like conventional, maybe better for angles? Maybe fewer clouds?) - High-volume, low-pressure? - Airless (all new equipment, no compressor?) Any thoughts? Anyone ever sprayed POR15 or Rust Bullet?
