heating the finish
It is much easier to heat the finish or warm the epoxy when you are mixing it with a small heat gun that is used to shrink the Monokote used to cover model airplanes. In fact most shops call it a Monokote heat gun. It will bring the bubbles right out. It also should accellerate the cure time.Your dad might have one. If not you can pick one up at the hobby shop in Redmond the next time your there.
Note of caution,,, when you are using it to warm the epoxy prior to use I warm the bottles before I put it in the mixing cups. I have blown to many of the mixing cups off my bench. Also heating the mixed epoxy will shorten pot life.
