Ok so I want to make some Garnet Shellac to finish a couple projects. I have a pound of the flakes, a gallon of alcohol, and a couple Prevals to spray it with. Now.... uh, what do I mix the stuff up IN? A bucket? The preval jar? Something specific I don't know about? Oh, and just at room temp, or do I have to heat it up to get it to mix? Thank you guys.
