Sanding the epoxy is a bad idea shortly after application. It is much better to use a scraper so as to not put the dust into the air. the uncured epoxy dust is especially toxic. The paint scraper does a great job of taking off drips too.

: I finally got around to applying the sealing coat of resin to the deck of my
: Greenlander Night Heron. I would have to call it at least a minor
: disaster. In some places the resin went on too thick, in other places I
: hardly got any on. My plan had been to put the fiberglass on tomorrow. If
: I do that will the blotchiness and uneven-ness go away with the first coat
: on the fiberglass? Or should I wait a couple of days and sand things down?
: I must have started with too big a batch, because the cup started to heat
: up before I got it all down on the deck. I'm using System 3 laminating
: resin with slow hardener.
