A couple things… the process of making Indian button lac uses a good deal of heat, and so polymerizes the shellac. It is technically not dewaxed, but it’s not waxy. And it does in fact make for a very hard and beautiful finish. tip – you can also add a drop of walnut oil, which also polymerizes [dries completely] and adds flexibility and a super nice gloss to a French polish.

Now, the only disadvantage I can think of is that it doesn’t have the same fantastic adhesion qualities that dewaxed shellac has. So I use *that* as a washcoat say between an epoxy sealer and a lacquer clear coat.

Hey all. I’ve used zpoxy quite a lot as a sealer both on open grain hardwoods, and soft woods to give it a bit of surface hardness. *Very* thin coats. Usually 3.

To combat any adhesion issues I’ve used a washcoat of shellac, before a clearcoat of lacquer or French polish. The disadvantage is how long each coat takes to cure.

Another possible disadvantage, if it’s not a very thin shell, is heat-creep when buffing. I was actually going to ask about west systems to see if it was an improvement on zpoxy for heat-creep.
