Not quite a duplicate of What are the best substitutes when nothing labelled as "Denatured alcohol" can be found in your area?
For my sins, I live in California. California has completely banned Denatured Alcohol, and you can't have it shipped here (so no Amazon or Rockler etc). Nor can you buy Everclear at more than 60%. Isopropyl Alcohol hasn't been seen in the stores since March 2020.
I need to either dissolve shellac flakes, or thin Zinsser premade shellac. Every website I visit just naturally assumes meths/denatured alcohol is available.
What can I use as a solvent in this state? And where can I get it?
