: Not being much a fan of the amber color of varnish either, I found reference
: to the Interlux 2-part polyurethane used by One Ocean kayaks on recent
: boats. Appears super-glassy, no amber overtones, and claims to provide
: good UV protection. Another plus (at least in my view) is that I could
: deal with subsequent touch-up on my own - not having to take it in to have
: an automotive coating re-sprayed seems advantageous.

The Interlux material indicates that it is intended for application over wood or epoxy so can probably be trusted for that purpose. I am not sure the same can be said for automotive clear coats. While they may well be suitable, I just don't know.
