This is cross-posted from rec.windsurfing, because people were talking about
Krylon paint in this group. Maybe someone has used it on West Systems epoxy.

Unfortunately, I have an instance of incompatibility for you, in fact, I am
trying to figure out how to deal with it. I reinforced a Mistral Diamond
Head's footstrap area with West Systems epoxy and then painted the whole thing
with Pettit Easypoxy marine epoxy, and the areas where there was West Systems
epoxy haven't dried (after 6 days!), whereas the other areas dried in 24 hrs
as claimed on the paint tin. The West Systems epoxy had been drying for more
than a week, and was well sanded after drying.
That's just for info: I had never suspected that it would happen.
Now, anybody know how to get the stuff to set? I figure the only thing I can
do is wipe it off with paint thinner (it is still that soft), and start
again. Some people have recommended Krylon epoxy paint: anybody used this
stuff on West Systems epoxy yet? I don't want another incompatibility.
