: Well, that's what I read for the 207: "An ultraviolet
: inhibitor in 207 helps provide a beautiful, long lasting finish
: when used with quality UV filtering varnish". Notice the
: " ... when used with quality UV filtering varnish"?
: Looks like the built-in is not enough. And varnishing seems to
: require something like 7 coats with sanding in-between (based on
: some JD videos I looked for marine varnish on wood).

: Does anyone know of a specific UV inhibitor additive that I can mix
: with my epoxy?

: May be I'm just overthinking it. My paddle will not see that much
: sun exposure to probably matter, I don't care about its color -
: only about the strength of the material. So I might just spray
: on a few coats of the automotive clear coat that I already have
: and be done with it... I highlly doubt paddle manufacturers of
: composite paddles apply coats and coats of finishes - I suspect
: they only use UV-resistant epoxy/hardener in the mold...
If you need that much UV protection I would spray the auto clear. Thats what I use on the wooden kayaks. It last for years and years on cars out in the sun every day. Just make shure the clear has good UV raiting of 40 or more. And it needs to be a high solids clear. It will have a mixing ratio of 4-1-1. kirk
