Use dewaxed shellac whenever you are gonna overcoat it.
Shellac with wax in it should be used only by itself. The
wax will reduce water resistance and also interfere with
adhesion of topcoats.

Was the shellac fresh dewaxed?


Not fresh, it was an old bottle of commercial mix. It seemed to harden OK.
Don't know if it was dewaxed, I'm no expert on shellac. I wanted a smooth
surface under the paint, and got it, but had to try something else. Would
dewaxed stuff be better? How can you tell if it is?
