I wonder if it would help curing to roll down some wax paper on the tacky
epoxy? Doesn't epoxy cure better without oxygen? Judy? The wax paper
shouldn't stick to the epoxy and should leave a smooth finish.

When the epoxy does cure, be sure to follow Judy's advice to wash it before
painting. After I rebuilt the plywood V-berth deck on my P14, using
epoxy-saturated plywood, the epoxy hardened nicely, but the paint I used
(Easypoxy one-part polyurethane) on top of the cured epoxy didn't cure for
weeks. I didn't know about removing the "amine blush."
