Hey Matt, this isn't a question about painting a car, but I do a lot of airbrushing and have a question for you. I use Createx water-based paints for all my projects, I'm not sure if you are aware of the product or not, but you can buy it at most any craft store in 2 oz. bottles. My aunt wants me to airbrush her motorcycle helmet, which I am confident in doing, but I was curious to see if you would know if I could use the createx paint (i'm trying not to use Urethane paints like House of Color, auto air, ect.) and I could spray a professional clear with hardener over my artwork to make in look 'factory painted' if you will.
