Well, far be it for me to disagree with a professional, which I most assuredly am not. But I do not think there is any wax in the stuff. It is acrylic. At any rate, cars have a tougher life, due to continuous strong sunlight exposure. UV tends to break down things quickly. I have used the stuff already with the Createx and Auto Air airbrush paints, and a water based dye that came with an Aztek airbrush kit I was given. Horrid little kit, actually. I have also used pearl powders in it with good results.
You heat-set it and topcoat like normal. Nothing new about the stuff for lure painting, I can tell you with great confidence. It has been used by many people for several years. The only thing I was wondering about is how many other folks were using it as a transparent base/extender, and which dyes or pigments they were using. That is really my question, not weather the stuff is suitable to spray as part of a finish on a bait. I already know it works great to "seal" colors between color changes, for example, and to give paint jobs a lustrous appearance. Another thing I use it for is to hide sanding marks on a clear plastic bait before I shoot any color, so I can spend a little less time on prep. It makes the bait look very clear and nice to receive the first coat of paint. Obviously, you still have to topcoat. My next test batch of baits will use the Art Resin as a topcoat, and I am looking forward to trying it out. SS
