I don't know how many of my builds were, if not ruined, certainly degraded and a waste of some hard work because of this problem. I use a lot of Testors Metalizer. No matter what I use to seal buffed aluminum, steel, et al, the nice, desired sheen I've carefully buffed is ruined. It seems the Metalizer sealer, put on very sparingly, should not flatten or otherwise made the metal finish look artificial and "model-ly", but it does. I can't afford alclad right now, and anyway I don't know if it has the same problem. I really like the toughness and natural sheen of SNJ, but it doesn't buff sprayed on. The buffing powder is really messy to use and it too loses its sheen when any kind of fixer is sprayed on it. I've never seen a foil covered plane that a) looked truly realistic b) could be done at a reasonable price. I recently tried to do it on F-86D and it was a disaster, though I used inferior, wrinkly Model Master foil. Any help would be most appreciated. I really want to do a decent looking Tamiya F-84 after my beautiful multicolored panels on the Pro-modeler kit were ruined by fixative.
