Hey Kevin,
I go thru gallons of epoxy tabletop resin from TWN industries in Fla. I use
it for bars, tabletops, and hundreds of skimboards.I wait about 20 min. and
then I "flame" out the bubbles with a propane torch.Try it on a scrap peice
of wood and you can get an idea of how fast to sweep the flame and how close
it should be.I've tried this with some epoxies and it didn't work (Ding-all
for example).For the skimboards I just thin it down with acetone.
Billy
P.S. The flaming trick worked great on my secondary.No bubbles at all.
