I've never used this particular spray gun but I'm sure you can spray Minwax with it. Minwax is very watery compared to latex paint so I can't imagine that would be a problem. Being a house painter myself, we use our spray gun for tedious work like shutters, lattice work, deck spindles, lawn furniture, etc. You'll find a million uses for it once you have it.I don't know a lot about painting, but I was wondering if you could run stain through it (as in Minwax stain I use on my bluckies). Right now I do them by hand and it seems to take forever!
