I forgot to ask in my previous question: in addition to shellac not fully dissolving in a weak formulation, are there other consequences to using a denatured alcohol with a less than optimal percentage of ethanol?
In the previous question about Denatured Alcohol, as a solvent for shellac I did not speak about drying time but predictable results will come when proven preparation (formulas) are followed with an understanding that weather and heat conditions (Shellac.net) will have an effect. It would be hard to state emphatically what that effect would be. This is why I always run tests of my materials before I touch a work of art. The short answer would be that the drying time of the shellac would vary and that “orange peeling” might or some other effect would occur, and maybe not in the short time. Martin Kotler, SAAM
