Renaissance Wax. Is there anything that Renaissance Wax ain't good for? I have been using it to polish and seal the surfaces of encaustics. CAUTION: Make sure the surface is well-cured -- a couple of weeks old -- before you apply the Renaissance Wax, otherwise you get minute -- I suspect chemical -- abrasion.
The Perfect Wax Melting Pot, at only three C's. I might try this instead.
