The hot coat cured overnight and looks... ok... although it will clearly need a pretty good sanding. Hopefully the gloss coat I'll add next week will go on better.  This morning I took a bowl of hot water and a clean rag and wiped down the epoxy to help get rid of any amine blush that might have risen. It looked like there was a little and I'll probably do it again later before sanding.  I intend to only sand the rail edges for now to prepare to glass the bottom and will let the deck cure fully for the next few days. Then I'll sand the entire board, top and bottom, later this week. Fully cured epoxy sands SO much easier than 'mostly' cured.  Today though, I drilled holes in the board! One for the vent and one for the leash cup thing.  This picture below is cockeyed and makes the holes look off-center to each other but they're actually pretty well aligned.  I had already drilled a vent hole before even gluing down the deck and then have kept the hole open wheneve...
