Well we all hear quite a bit about the evils and wonders of both
polyester and epoxy. But what about vinylester? Any one ever use
that? I'm curious because
I saw a vinylester/kevlar canoe prototype by Mad River Canoes that was
20 years old, light as a feather and showed hardly a scratch though it
had been dragged through gravel for years

Not a single one anymore...

Even most of the kit manufacturers have changed over to epoxy.

OTOH, there is a growing use of vinyl ester resin.
It is catalized and works a lot like polyester, but with better
chemical resistance and much better physical properties.
