I just put the amount of alcohol I think I need in a cup and add flakes until I get the shade/consistency I think I would like that time. One coat for existing, two coats for new tape. It's going to be runny/drippy anyway. No leftovers. Like baking. Haven't made a full recipe of cornbread, biscuits, pancakes in ages either. A little this, a little that, just like Grandma
