Most of the talk about HVLP that work with smaller compressors points to Harbour freight. But they don't exist up here. Any chance any of the branded products might work with a 4.5 cfm 40 psi compressor? I've seen some talk about a Porter Cable unit but it offically requires 8 cfm.
A local place called Princess Auto sells a couple of guns that sound interesting. One claims 3.5 cfm average 13.9 continous. Does that really mean it's a 13.9 gun ? With 3.5cfm only if it's turned off 75% of the time? The second gun claims 6 to 8 cfm. The discussion in the archives is that it's possible to get by with less then the stated air requirements. Anybody think that's nuts?
FWIW I'd like to spray shellac and enamel. If it handled Latex so much the better but it's not a big issue. Usually nothing bigger then a bookcase. Not very often either.
