There was a guy who we would see at the SIG contest each year who was from the Des Moines, Iowa area that had great finishes on his models and used just about everything under the sun. I believe his name was Sam Scirata, and might have the spelling of his last name wrong. he worked in the custom auto painting business and had access to all kinds of stuff, including ground glass that he would add to some models. They were dazzling to see in the sun shine. The biggest concern as I remember was that it was impossible to get a light finish this way because as was already mentioned, it takes a lot of clear to make all of this work. To get the flake and other stuff to spray, you need a big gin, and that means a lot of paint goes down just to carry the additives, and then add in the clear. I don't think Sam ever had a model that weighed less than 72 ounces or more and these were all ST.60 and tuned pipe ships. Shooting dope this way wouldn't be too different from regular lacquer I would think since they are from the same family of paints. You could keep it to a minimum by just applying it to trim colors and such. What Sam was using was 30 some odd years ago technology, and maybe there is something new out there to try these days. Good luck with it!
