Among errands and other things, I did get the laps from the top deck lamination ground down on the 4'10". On the back corners there are some voids that opened up with the grinding - over wraps from the laminating (should have cut more of the excess fiberglass and carbon off before laminating). I'll fill both of those with some tinted epoxy, then I'll get the fill coat placed on the bottom deck.
I got farther than what is shown on the pictures. I'll take a 'before' picture before I start getting the fill coat on the board.
