I have searched for an answer to these questions, but still don't know what to do. I am buying an HVLP gun that comes with a 1.3 tip, and I was thinking of getting a 1.7 for priming. I was also considering getting a mini gun which I see uses smaller tips. My question is, what tip sizes are are appropriate for paint and primer for the mini gun? Do the same size tips produce the same results regardless of gun size? Thanks in advance.
