I scored a nice rear step bumper today

Off the truck,brackets pad, and even the rear plate lights. Beautiful shape 1998.
Glad it was off,it's only 14 deg. today.

Anyways, wondering what would be a good product to coat the inside of it with to keep rust at bay?
My other bumper just had paper thin chrome in a couple places.

Rustoleum makes some rust preventative spray, and some other companies.

I'll get a couple pictures tonight and post.

Been looking around on the web.
The Eastwood Rust Encapsulator Paint has high marks.
