It sounds to me as if you might have been a bit over-enthusiastic with the squeegee. I haven't used 2 oz cloth, but it doesn't give you much to play with between the wood and squeegee and might therefore get air in the mix quicker. Otherwise, it might be a reaction of the epoxy with an incompatible glass coating, but I would bet on the first.

: I am building a CLC kit Arctic Hawk. The directions call for glassing the
: interior of all the panels then building the hull and glassing the
: exterior. So I am trying to follow the directions, I have glassed the
: interior of the deck with 2 oz cloth, and it looks milky in places. Do I
: have to sand it all off and start over. All I am interested in is the
: structural strength the way it looks is not a big issue because few will
: see it. However, I want do figure out what I did wrong. I mixed using the
: pumps supplied in the kit, not sure if I mixed the two parts too much or
: too little. They looked OK in the cup and as I was applying the epoxy. The
: 2 oz was a whole different deal than the 4 oz I have done before, which
: all came out OK. Did I over work it and get air in the mixture? Could it
: be an issue of dew on the surface? I did the work at 11 pm and left it out
: on the driveway over night. Some of the glass that overhangs the wood
: looks milky as well and some of it is clear. Sure don't want the deck to
: collapse and also don't look forward to sand off all the glass. If I have
: to sand it all off what is the best method to use? Thanks all, I would
: show you a picture but no digital camera
