The Midwest Aerogloss Clear in the larger jar came well after the original Aerogloss that Pactra put out. They marketed that and sanding sealer aimed at the Pinewood Derby market when it grew several years ago, and instead being a one time of year thing, goes on almost year round now and isn't limited to the Cub Scouts. They never marketed colors, that I can remember. Regular hobby shop spray paints would go over it, as I recall, but don't remember if it was the enamels or the lacquers, as both are available. When I worked at a local Hobby Shop, we carried it for a short while but then became unavailable. The biggest advantage of the Midwest product was it came in small bottles and the 4 ounce jars. I think their thinner was only packaged that way also at that time. With SIG products available at the time it was no big deal. It may very well be an acrylic lacquer. I never tried it to see if it would hold up to a fuel spill. The original Aerogloss was tough stuff, and it was "hot fuel proof" as far as I can remember. . That's what others have remembered about it also, and another reason for finding what they need to restore an old model if they intended to fly it. Just test it thoroughly and if any doubt, save it for small jobs where you can use it up. If it is in the acrylic lacquer range of things. SIG, Brodaks, or Randolph's may go over it, especially if you let it gas off for a couple of weeks.
