Hopefully someone out there will be able to help us. ASAP. I want to get my boat in the water soon.

: I'm finally able to apply skim coats of epoxy over my hull after a few months
: of off time.

: Before I applied the first "fill the weave and small hollows" coat
: I roughed up the areas, wiped down w/acetone, scrubbed with warm water and
: a green scrub pad (no soaps or oils in the pad). I then used my sqeegee
: and filled the weave and low spots. Not perfect, but it was the first of a
: couple (I figured). After curing 4 or 5 days I decided to use my fairing
: board and take off some of the high spots so I could add another skim
: coat. Well, it seams at the edges of the previously applied skim coat
: (where the sandpaper went through like it was supposed to on the high
: spots) the edges are flaking up. It's not really noticable until I wipe
: down with the warm water and scrub. I can peel super thin layers off. Has
: this ever happened to anyone here? Is it something I should worry about
: now, or can I just add another skim coat? At first I thought it might be
: blush, but wouldn't that get removed w/my prep? Then I thought the
: acetone, but I wiped down with water and scrubbed.

: Thanks for the help. Right now I'm somewhat dejected at the time I've wasted
: if it all must be ground off.
