I do. Salts and Thinly cut Shellac are used to create the Zero finish base into the wood. Single coat of pure Lacquer (no oil plasticizer) is used to seal it since Shellac can't be used by itself as a protective barrier from the elements. Any brand that will sell you pure nitrocellulose lacquer is fine. Use acetone or lacquer thinner (or mix both) to control gun flow or open time and oil if you want a more flexible coat without checking. I also use lacquer retarder as a final coat to melt the surface smooth.
