I tried Stewart’s and had nothing but bad results. Orange peel or solvent pop. We went through 4 cans of “practice paint” and a gallon of white and never saw a professional finish. I talked with their experts and we tried everything imaginable with gun settings, pressure settings and paint mix. We even had a chemist look at this paint. Our air system is on par with professional systems and the gun is an Iwata LS400 SuperNova. We put together an 18 page report of our results and sent it to Stewart’s. They didn’t have any answers. After talking with a kit manufacturer and a certified manufacturer at Oshkosh, I threw my Stewart products in the trash, even the Ecofill. At almost $400 a gallon this paint should perform flawlessly.
PPG is the way to go. Yes it is solvent based, but you will get professional results every time.
My 2 cents...
