Durable clear finish for timber window?

[fobos8]

Hi there

I'm making a window for a summer house from Accoya. What is a good transparent finish I can use?

I want to apply something and then forget about it for 10 years or more. Was thinking Teknos range but they all spray applied. I'll be applying with a brush.

Cheers, Andrew

I think you might struggle with that, especially in a marine environment.

heard good things about linseed oil paint for being long lasting outdoors, haven't used it personally but it supposedly lasts decades.

Epoxy followed by varnish for UV protection...
