My favorite painting method is using a simple airbrush (Badger 350) with Createx acrylic paints (primarily the Wicked Colors). When Im done with the color, I have been clear coating with Rustoleum 2X Cover Gloss Clear. I really like the control I have with the airbrush (both control of the paint and the environment being inside with the water based paints). I need to spray the clear coat outside and it always seems like Im fighting with various particulates, bugs, etc. Im wondering about some of the water based urethane/polyurethane products and if I could spray them through my airbrush. Also, how they perform in terms of durability and being able to sand/polish/wax to a high gloss finish. Anyone have experience doing this, or general working knowledge of waterbased urethane/polyurethanes? Thanks.
