In Response To: Epoxy: Uneven epoxy and little craters (Mark Sheeres)

: Hi,
: A few more questions about my epoxy troubles. I put the second coat
: on the inside of my Chesapeake 17, and when it had hardened I
: noticed what looked like little tiny moon craters, about the
: size of BBs, where it seems the epoxy was not adhering.
: Background: the first coat had gone on about a week before (did
: I wait too long?) and it was really uneven with some drips so I
: sanded it trying to smooth it out best I could. Then I removed
: the dust by blowing it out with an aircompressor (with the kayak
: upside down) and then wiping it out with a damp cloth, and
: allowing it to dry overnight before putting on the second epoxy
: coat. I am using MAS slow-hardening non-blushing epoxy. It was
: applied with a foam roller and tipped off with a foam brush.
: So...what caused those little craters?

: Also, what is the secret to a nice smooth coat of epoxy?? Mine
: turned out really uneven, there were some runs, and it just
: looks really ugly.

Also there is the possibility of blush. There's no such thing as a non-blushing epoxy, there are some where it's less of a problem but any epoxy can blush. Regardless of what the manufacturer states, have to always check your layups for that oily/waxy coating.

I suspect though that the other guys are right, that you have oil left from using the compressor.
