: I like to warm my epoxy if I am wotking where its under 65 F.

I think the thin coat of epoxy is going to be the same temperature as the wood or glass you are applying it to a few seconds. If you want to wet-out thoroughly heat your shop and everything else will keep the resin thin.

It's not just keeping the resin thin during wet-out but keeping it thin for as long as possible. I've had wet-outs where there were bubbles or a haze I couldn't get rid of, but because I heat my shop to 85˚ use small batches of resin, and slow hardener, the bubbles have a long time to dissipate, and they do.

From time to time I hear people talking about bristle roller covers and every time I've tried them they produce lots of foam, more so than the West System foam roller covers. But in any case the key is to go over the surface and tip-off the drips, runs and bubbles with a dry foam brush.
