I've had a bit of a set back with the epoxy coating I've done over the last couple of days. I came to give it a sand today (36 hrs after the last coat went on) and the top layer started to flake of - like sunburnt skin. It looks like the third coat didn't bond to the first two which seem to have gone on well. In the photo the area to the right has already been sanded back - the framing in the centre of the photo has had a swipe with 220 sand paper.

I put the third coat on 12 hours after the first two, which went on 2-3 hours apart. Either I didn't mix this batch right or the System Three SilverTip claim that "Subsequent coatings applied at any time between this soft set stage and 72 hours do not need to be sanded and will chemically bond." is now looking a bit questionable.
I'll sand the bulkheads and transom back over the next couple of days and then give them another two coats each.
