Painting Stainless Steel

[Jaws]

I'm building a light rack out of stainless steel to hang my radions above my aquarium but the stainless is just food grade so it still would eventually oxidize over time. Anyone know if you can spray paint this product over the steel to protect it long term without any ill effects on the tank? I wouldn't imagine so but wanted to be sure first. It's basically that spray that they say you can spray over holes in a boat to seal it again. Not that I would. Lol

Thanks for your help.
