re: 2 Part Epoxy Substitute

With System 3 epoxies (other formulations may not behave the same), TransTint dyes lower the surface tension of the epoxy enough that I get almost bubble-free pours with no vacuum or pressure pot. I do, however, get lots of leaks if I don’t do something to seal it all up before doing the big pour, so I tend to paint a thin layer of clear epoxy on the pieces parts to make a sealed unit, then do a second tinted pour to fill the volume.

The few remaining bubbles I pop with a propane torch. But then I’ve got an open time of almost an hour with the hardener I use after adding the dyes, so there’s plenty of time to deal with the few bubbles.
