Those of us that use epoxy for pore filling might find this article enlightening:

Depending on the epoxy used and the amount left on the surface it may be more or less of a concern.
Great write up about the epoxys.
I wonder how the epoxy holds up under UV relative to nitro or some of the other finishes. My question would be how have the top coats held up before the UV exposure really affects the thin layer of epoxy left on the guitar from the pore fill. I have four fiberglass kayaks and they get hundreds more UV exposure than my guitars.
