I've gotten my butt in a bind on a finishing schedule for a wedding gift. I've either run out of or misplaced my blonde dewaxed shellac flakes. I seem to remember the Zinsser spray is also dewaxed. That is all I have access to locally. They also sell Deft, but have never used it as anything other than a finish coat.
Fwiw, the project is a walnut Butler's Tray Table. I usually apply a coat of darker shellac (done), dark grain filler (done), a couple of coats of blonde shellac, then my finish coat which I would like to rub out.
