Protecting drop down frame

[luv2fish]

I bought a house last year, and used it alot in the winter. I am also stuck with having to keep it outside year round. I notice that the frame is already starting to look rusty. What can a do it yourself guy do to protect the frame. I am thinking that I need to get a wire bruch and scrape as much loose stuff off as possible. But then what would be the best thing to spray on to protect it?

Thanks!

Herculiner. The do-it-yourself brush or roll on truck bed liner. Very tuff stuff for the price.

Where can you pick that stuff up?
