Harbor freight purple hvlp
I just purchased a Harbor Freight cheapo hvlp gun and throughly cleaned it. I have NEVER sprayed finish before.
I tested it using my 2 1/2hp 10gal compressor, which is supposedly rated 6cfm @ 40psi, which is what the gun calls for.
I practiced using sealcoat, which I thinned, but can't remember by how much, because it was left over from a different project (brushed).
The sealcoat laid down beautifully, however, when I set everything up and made adjustments to the gun, the air would constantly be going thru the gun, and when I pulled the trigger, a nice coat of finish came out.
My question: Is it normal for the air to be constantly flowing thru the gun?
It seems odd to me and it seems that I am just wasting air that my small compressor may not be able to keep up with. It did kick on while spraying a small cabinet door.
Thanks for helping a newbie sprayer.
