Hi all, I have read the previous posts that I could find. I've got a Harbor Freight HVLP spray gun (this one), and am planning on getting a small air compressor, probably this one. I know it's kind of underpowered but I think it will be OK for spraying some raku patinas or terra sig, based on reviews. I don't want to make a huge investment in something I may not use that much. I am trying to figure out the hose and fittings needs. The sprayer recommends a hose of 1/2 " internal diameter, but it looks like I need to get a 3/8" hose with 1/4 inch fittings? Does anyone have advice on hose diameter? How long a hose do you use? I can plug the compressor in my kiln shed and spray outside, but don't want to get too long a hose. I can call Harbor Freight to ask about the fittings, but it's confusing. Something like this with a 3/8" hose?
