I was thinking about that, too. I once did railings
in a condo development where the owners had got
an epoxy paint. I never found out what the stuff was.
It went on thick and created a nice shell for the
pipes used in the condo deck railings. But I did it
in hot weather and was only getting about 15 minutes
out of a batch. That's one notable limitation with
epoxy: One can ruin a lot of work before getting just
the right mix and figuring out how long the open time
will be in a particular scenario.

I've noticed that there's also such a thing as
"one part epoxy" paint lately. I have no idea whether
it's any good. It sounds to me like a misuse of the
word epoxy for marketing.
