I only painted one job mate used 2 tips 1.3 and 1.5 ( drilled a 1.3 tip to make the 1.5tip) . Used fir epoxy primer, 2k single stage, abd 2k clear with 15-22 psi range . It’s a amazing spray gun very similar to the pro lite but build better . I have also noticed the inside air valve seal/plunger 2 get stuck like the pro lite
