Krylon ColorMaster Spray Paint

I own a 3D printer and needed a better paint to paint my models with… I own an airbrush and the paint was too fragile for the parts I am working on (parts will rub on each other and be pressed together repeatedly) so I switched to this and I was amazed at how clean the paint dried on the pieces. The plastic is PLA and the surface finish is PERFECT (I wet sanded it anyway to ensure its smoothness) and with the top coat it SHOULD be impenetrable to scratches (I used 2-3 coats of the paint on the parts). I also let it sit for a week so it can cure to the plastic. I will be using this over Rustoleum. And I need more…
