You can also hand rub a coat of "tung oil finnish" over shellac to make it more solvent proof. Looks identical IMO to shellac and it works over the bullseye or zinger stuff ( i think its dewaxed)
The only Shellac I can find is the Zinsser stuff. Is it any good? I've been reading that you have to thin it or it dries too fast. I have Tung Oil already, but it looks nothing like Shellac. Of course, I don't have the pure versions, they all have additives to make them easier to work with.

Thanks for the free stock

It wasn't that pretty but it cleaned up pretty well.
