I've been using interlux brightside for a while now and it works ok, but I was wondering if it's possible to epoxy resin as a topcoat? Since it is very durable and waterproof I figured it might be worth looking into. I know the downside of the resin is the sun can break it down, so is their something I can add to it to stop that? maybe a UV stabilized tint or something?
It's to late to use it on my current project, but in the future it might work for me.

There are additives, but it's cheaper to overcoat the epoxy with a spar varnish.
Long term exposure to UV eats epoxy. But, if garage kept, the epoxy holds up well.
The only difference after a year, is that the epoxy on the Slipper has darkened.
Now it's a darker, more golden tone than when originally applied.

There are UV resistant epoxies for surfboards and sailboards
Not cheap, but neither is regular epoxy.
