I'm going to prime the internal parts of my RV-10 for various reasons. The primer I've chosen is AkzoNobel 463-12-8, as I have a reliable supplier around here for it. The problem is that I have only a 20 gallon 2 HP compressor that I'm not inclined to upgrade. Assuming that most surfaces I prime are going to be small, is there any spray gun I can get that will do a decent job. I'd like to get the Accuspray, but it seems to be HVLP and requires 13 CFM @ 20 psi. The best my compressor can do is 7.1 CFM @ 20 psi. So that seems out of the question. Astro Tools has one called the GF14S that seems to suggest it needs a 3HP compressor, but the flowchart on their site also seems to indicate that if it can pull 5.5 CFM @ 50 psi, that it should be sufficient, and my compressor can pull that. Anybody that has a smaller compressor had any success with any spray guns in particular?
