Need paint for Trailer fender

[brianct12]

Thanks for all for the advice.
Had to go with steel - total cost was just $80 for the pair. I am thinking alike with Willy. Am thinking about a first coat of galvanize spray - then I think followed by a few roller coats of Line-X or Tuff-Coat or similar product on the underside to give some toughness protection from road debris. Maybe I'll even coat the topsides with that stuff.
