Nuts!! Wish I had known about the saran wrap trick. I did try and "squee-gee" the excess away, but I bet using the Saran wrap would have helped, too. Especially with minimizing or eliminating the need for sanding.

And I didn't thin it with anything, and didn't need to use the heat gun - it got fully saturated on its own. I was nervous about using the heat gun anyways, as I was worried that I'd get it too hot and the rxn would speed up and it would set before I had it exactly where I wanted it.
