I've had excellent luck with Rust-Oleum products. They make marine paints that are area specific. Stuff's readily available .. you can pick it up at Blowe's .. I don't know if Home Dopey carries it, however, they probably do.

I have a friend that has used this on his deck ... Seems as if it lasts. I believe he put it one around five years ago and it's still going strong. It's a non-skid coverage and it looks kinda neat.
