varnish over epoxy

hull #99 was finished with varnish over an epoxy sealer, the idea is that if
the maintenance is neglected and the varnish fails that the wood will not be
subject to weathering and turning black. has anyone tried this or know about
it? it sounds like a promising technique, but i suspect that if it did not
some significant disadvantages, that it would have taken the world by storm
already.

Varnish over epoxy is the method by which the majority of wood strip
canoes and kayaks are finished. I’ve done a lot of web surfing and
reading on this myself as I’m about to start construction of a wood
strip sea kayak. The theory is that epoxy needs protection from ultra
violet rays. Modern varnishes contain ultra violet inhibitors. The
finish looks beautiful on the boats that I’ve seen. The only caution
I’ve read about is that you need to make sure that the varnish you
choose is compatible with expoxy. I’d say that it’s a very promising
technique and something worth looking into.
