Also, all my shellac in flake form are about a decade old. They are Liberion: Dewaxed Orange and Platina (Platinum Blonde/ Extra Pale Dewaxed). I decided it might be too old to use. I did mix up and use the orange (brushed on) on a temporary countertop underneath a General Finishes High Performance Top Coat as a test piece. It performed fine as did the GF top coat … it’s in use now on a temporary counter top that sees harsh use and the GF performs better than I imagined.

I too considered shellac in a can as infra dig … however I read some very promising things about Zinsser Sealcoat, esp. from authors who had no financial motivation in selling shellac or ideological dogmas to defend … in fact some touted its superiority for seal coat/barrier coat/washcoat purposes due to the mixture, the ease, price point, performance … and shelf life (how do they blend it to extend the life?). I can’t say as this is the first time using it.

I’ve only ever used shellac for sealing or toning wood under colorless water base top coats. I’ve never French polished anything. I’ve also used it as a sealer or utility topcoat on many items over the years where looks played no role.
