Here is what Great White North (Geoff) said in a recent post (permission granted to paste here):
"Here’s what I’ve done lately, with great success; calculate approximate glass weight.
Mix resin to 1.1 times the weight of the glass. Apply resin with a foam roller; not a squeegee. Same techniques apply though; when lapping, start in the middle of the board and work towards the end, pulling the lap towards the middle of the board so that the fabric stays tight.
Let it kick for about an hour - 1.5h (this is for RR, at around 70F, with the fast hardener). Seems that any more than 2h and I start to see fisheyeing and other weird stuff going on. I also use a different resin for cherrycoating; EX-74 from eti-usa; still an epoxy, but a casting epoxy with better flow characteristics (MAD viscous)
Go back and cherry coat using about 2/3 the amount of resin to fill the weave. Let that set up over night.
Sand back the area you plan on lapping to the following day.
Glass the other side as described above, with cherry coat and all.
Let it all set up for another full day.
Sand the whole board. Don’t go past 120 grit.
Then apply your gloss coat. You should be able to get away with almost half of the amount of resin you initially used to wet out the glass and still get good coverage. Make sure to wipe the entire lam down with Ethyl alcohol before applying any resin and once wiped, it’s glove only zone. I usually tape off a seam, then pull the tape once the resin has kicked, and tape right along the seam after just barely sanding the seam bead to insure good adhesion.
That’s about it; I usually leave the decks as is unless there’s been serious zitting and I start sanding the bottoms and rails at about 220; sometimes 320 if the gloss coat went down smooth, and go all the way through to 1500 wet. I like the sanded bottom…I’ve gone as far as the full Macguires treatment, but haven’t noticed any performance enhancement and honestly, epoxy just doesn’t get hard enough to polish like poly…but then again…that’s why it works so well as an adhesive.
Copy and paste whatever you like my friend.
Cheers,

Again, are you all using the fast hardner or slow? I’ve had zero fish eyes with slow and tons with fast.
