WARNING! Years ago I used shellac as a sealer for plates and after a few years the finish started to crackle and in some cases peel off in sheets. I found the solution in a product call Silicone Stop Sealer which was made by Mohawk. I have two gallons left... but I called the factory and they put me through to a chemist who told me that it is half shellac and half lacquer. The way I use it is to spray on as an undercoat then when it is quite dry I spray Utilac gold in a spray can... this alas is discontinued as well. Then I mix about 1/3 orange shellac with the silicone stop seal and overspray the gold starting with a very thin coat then spraying until the right golden hue is had... I love the look, warmth, and feel, especially in tungsten light.... I treat the Steinway action rails the same way and it looks almost like polished brass.....but without the eventual tarnish. Shellac reacts with metal and I had some bad experience mixing shellac with the powder but I think some experimentation with lacquer/shellac is worth while...
