Acetone is quite commonly used in industry as a working thinner for epoxies with no, or few, ill effects on the final cured resin.
I do admit I don't have 14 years of coating experience but I did have more than just a few semesters of polymeric chemistry.
Below are pics of a quick trial done this morning.
Harbor Freight PC in an acetone vehicle.
Shot from an old Paasche double acting air brush. -No- clogs were encountered.
Baked at 400F. The coating seems to be as tough as any other I've done. Actual shooting will tell the truth on this. Would I do 1000 boolits this way? Nope.
