Make sue you warm up the epoxy to lower the viscosity. I actually get mine fairly warm. It will kick earlier but I work fast. And let it soak for quite a while before you squeegee. Use many smaller batches rather than big batches so the epoxy doesn't thicken too much before it has a chance to fully wet out the cloth. Work fast. Any weight glass can be wet out with enough time and thin enough epoxy unless there is a coating on the glass which can happen but not often. Over the years 4 oz has proven to be plenty enough for a stripper with the extra football shape on the bottom.

Whenever I try a new glass supplier, I wet out a scrap first as a test just to see what I'm up against.
