I made a trip to Costco after cleaning out the middle of my garage. I got a BIG bag of 20 oz Dixie cups for mixing up my epoxy. If they won't work I can use em for drinking purposes. They do not seem to have any wax coating and do have a flat bottom that is fused to the sides--pretty standard stuff.

Is there a better and cheap option?

Also, building an Arctic Hawk kit--how wide a building surface do I need?
At the moment I have a sheet of plywood on two horses and intend to put two extension ladders under the ply to glass all of the pieces prior to assembly.

Thanks gang, and here we go.
