They call it exterior paint. Works well on houses too.

Spar varnish if you want to see the wood grain. 2-3 coats would look great.

Problem with that is its going to need frequent refinishing... like every couple years at most. Why I did not recommend it for that application where direct sun and rain will hit it constantly.

If there was a large porch protecting it I would say otherwise.
