Maybe nothing but how are you mixing the epoxy? On my first boat I did it like beating eggs and made bubbles that way, then eased up realizing I had time. Second problem I had was over working the roller or brush, I couldn't leave well enough alone and thought going over it more with the roller would be better.....I caused more bubbles and defects.

: As always thanks for the advice.

: I went ahead and used the use the foam roller to apply the most
: resent coat. It lays down a lot (I mean a lot) more epoxy than
: the squeegee method. it was about 2 to 4 times more epoxy than
: with the squeegee, Also most of it stays on the boat instead of
: half of it ending up in your scum bucket or on the floor. I will
: half to sand it and fill all of the bubbles left by the roller.
: After dragging a foam bush over it off and holding a space
: heater on it (that it all I had) it looks like a zit riddled 14
: year old one to two bubbles per 4 in^2.
