Hi. i am looking at a couple of spray guns. They are a off brand pair of guns. i am on a pretty tight buget, so if I can cut a few corners.. I checked into having the 37 painted this next Summer. The only place in town that will shoot it wants $450. I have to supply everything. I went to school for auto body repair in 1971. I used one of those guns with the cup on the bottom. I remember painting back then, but can't remember how much thinner and such. I am looking at those HVLP guns. One of the guns has a 1.4mm tip for top coats, a 1.8mm tip for primers, and a 1.0 tip for detail. They are from Harbor Freight Tool. On sale for just under $50.00. I plan to paint the 37 a blue that I once had on a 1970 Dodge Challenger I had way back when.. I will have to look up the name of it again though.. It is a metalic.. Thanks.. Al
