I tried a foam roller, and the bubbles were horrendous. Spraying would probably work best, but the epoxy I'm using has a tendency to run easily. I don't have enough spraying experience to work with this material (it'd be really touchy, runs at every opportunity).

Brush leaves mild streaking, I'm going to try a thinner and softer brush (nylon though) tomorrow. The chinese bristle brushes that we have been using are too thick and stiff.

I haven't tried warming w/ heat gun to explode bubbles yet.
