Thanks folks.

I tried heating and even got it out under some sunny days this week but to no avail.  There is still a slight tack in some areas.

The varnish manufacturer got back to me and confirmed no compatibility issues with overcoating West System epoxy....unless.....I over dosed the hardener.  Given that it is only certain patches, which were certainly different batches of epoxy there could be something in this.  Although I measure out using syringes so I am pretty darn accurate.

Anyway his solution is to dry sand and wipe down with acetone and put on another coat.  We have some warm sunny days coming so that will be the plan.  He reckons it will be OK.

My thoughts are the high humidity might have been a factor too.

I think a certain cobber on this forum whose name starts with G might have warned me that he doesn't bother with all the fuss of epoxy sealing then overpainting.  Maybe I should have listened hey?
