RE: Reusable Epoxy tool
I like to use the little food sample cups and spoons that Sam's Club uses. I ask if I can go thru the trash cans and get a dozen or so, then take them home with me and clean them and re-use them. The cups will hold more than you usually will want to mix at one time, and the little spoons make neat applicators to dip and spread the epoxy. Afetr you're through, throw them away (again).
