This is the first time I've worked with shellac, and I'm spraying it over an transtint dye that was followed with an application of wet-sanded danish oil to pop the grain and fill the pores. I let the danish oil cure for three days prior to spraying the shellac.
I'll be following the shellac with an application of sprayed pre-cat lacquer, several coats that are tinted. The shellac is serving mostly as a sealer over the danish oil, to isolate it from the lacquer. It's also serving as a sanding sealer to allow me to polish out the base layer before the lacquer is sprayed.
I am planning two coats of shellac. How much can I sand it down between coats? Can I go at it with the RO sander and a 320 pad? I'd like to smooth out the panels quite a bit. Do I need more than two coats?
