Has anyone tried or know what would happen if you applied a
polyurethane product over epoxy when the epoxy was still tacky. Would
the adhesion be better? Would it intefere with the cure of the epoxy?
What about a latex primer over sticky epoxy? Anyone try anything like
that to try and get a better adhesion to the epoxy?

I once tried that trick with coal-tar epoxy and copper anti-fouling.
Cleaned the propeller real well and applied coal-tar epoxy. Waited
until it got tacky and slathered on the copper based paint. The next
trip most of the paint came off, just like it always does.

As far as I can tell there is no problem in making paint stick to
epoxy.I usually make sure that any blush is cleaned off the epoxy and
then fill, fair and prime with epoxy based materials and apply a top
coat of two part polyurethane. My sloop is going on ten years now and
still looks pretty good.
