Laquer thinner will degrade the plastic parts and deform them, mineral spirits is mild and better for plastic, these guns are good for anything that can be cleaned with just water otherwise it's a waist of money,,,,,,or for a one time use.
One thing that you forgot to do was to clean thar piston slot. Owners manual says to clean it spotless or the piston will get stuck. Happened to me already
How do you know if it's getting stuck? Noisy? I can't get paint to come out. I used mine then cleaned it, then stored it for a long time and now no paint will come out.
