I had some problem with fisheye on an old boat I was revarnishing. I scrubbed it with a solution of Simple Green cleanser and a ScotchBrite pad then rinsed thoroughly and the problem disapeared.

: Seems my note left some issues unclear. I'll try and explain some.
: I took an old bed sheet that had been washed (read very clean). After spaying
: off sanded epoxy, I sponging the yak with water running over it, I wiped
: off the drying surface with several rags (sheets)in a swirling motion
: (polish-until they became soaked and I got a new rag-overkill) so as to
: rub off any sanding residue compacted in the pores. The cups were new and
: I'm used to molding chemicals/agents, none here or in the liquid transfer
: items. Yak built with epoxy over fiberglass, and a final finish coat of
: epoxy ready for varnish. Never did varnish. 1 month epoxy cure pushed me
: into winter (rain) that year. I blew off the varnish in the spring. Used 8
: times that year. Winter. Now spring. New coat-fisheyes.

: After all this, I think the problem is river residue that wouldn't sand away.
: I must missed a needed solvent wash.

: Thanks to all for your bits of wisdom :-)
