RE: epoxy mixing containers
Ken,
All you really have to be sure of is that the container has no wax. In my production I use 2 oz Dixi solo bathroom cups. They are cheap and unwaxed and available almost anywhere. Rarely will you mix up more that 2 Oz of epoxy unless you are doing a large layup. Fiberglass layup has a learning curve... just take your time and read all the instructions multiple times. The mistakes are REALLY troublesome and time consuming.
