Pete,

By far the best stuff out there is Createx Auto Air. There is a ton of information available on them. They do require some special handling just like any water base paint. They need to be put on with light to medium coats and let dry before you hit them again. In other words, they need to be built up. You can't just lay on a heavy wet coat or you will have big problems. The folks at Coast Airbrush are experts on the stuff. There is a major shift in the car and motor cycle graphic guys to water base. The stuff has advanced to the point that is just as good as solvent based.
