If you're using an epoxy that blushes, first wash the sealer coat. Then just rough-up the surface - you don't want to sand down to bare wood or you'll get some color variation with the next coat of epoxy. I use a Scotch-brite pad to scuff the surface. If it snags, make sure you get all the green bits off before applying the glass. Once scuffed, wipe off the dust with a cloth damped with denatured alcohol. When the hull's fully dry, glass away.

: Hi all: I just wet out the hull of my Great Auk with epoxy, and due to time
: constraints (I'm in my 4th year of medical school, and they want me to be
: in the hosptial a LOT, not home working on my kayak) it will harden
: completely before I get a chance to glass it. That's OK with me, because I
: kind of wanted to sand it a little anyway. The question is, how much
: should I sand it? Should I just rough it up a bit all over? What grit
: should I use? Is my random orbital sander too much power for this? Nick's
: book wasn't exactly clear on this part, because it advocates skipping this
: step, or applying the glass after a shorter duration before any amine
