Thanks! I thought this thread had crawled away.
The best wax suggestions mentioned to me were shoe polish and also car wax. But no one was certain if the epoxy wouldn’t have a reaction with the wax and end up absorbing some of it or leaving some on the surface. Ultimately I’m going to glue the part I fabricate into another part and can’t have a coating on the fabricated part that will interfere.
Some suggestions at another site got me to look into using some mold making material and then easy casting epoxy with the mold
The best candidates for the first round of mold making anyway are on the link below, and the casting epoxy is made by a few different vendors.

There is also a variant of casting epoxy by one vendor which doesn’t require exhaust ventilation and a full face respirator to use.
The tools above are actually less expensive than the epoxy glue I planned to use and will probably provide at least identical results.
