Visit this site and have a look at "Smart Coat". I made a steel handrail that lives outside with nothing else but this stuff on it and its been 2 years and still no rust! The best part is you just wipe it on like a wood stain and you're done. Works over rust too so you can capture a patina and once its on it just gives the metal a wet look.

Those guys are out by me. Really nice guys: I worked with them a little bit when we put together our regional blacksmithing conference a little while back. It's always awesome when you come across a vendor who has it all, knows his ****, and is also really nice to deal with.
