The latest issue of Epoxyworks arrived here today.
There's a very good article called:
'Bubble-free Coating' by Mike Barnard and Don Gutzmer
I've been using epoxy for 30+ years and I learned a couple of new tricks from reading their article.

BTW, the subscription to the twice-yearly print edition is free (in Canada/US??).
