OOPowerStrokin,
Lone Ranger here, Look I can tell you what we use in Oz... And they are products that you can find in the U.S. They all work by cutting off oxygen to the rust.. Water feeds rust, the free O2 in the H2O.. Anyways, they all work by sealing off the rust from oxygen and water... One is a Valvoline rustproofer, and it seems more of a waxy based brown spray. Then there are a variety of Fish Oil products that go on like a varnish, and dry to seal it off.
Then there are a variety of Products that have phosphoric acid in them, like the "Rust converter" types....
My best suggestion is remove all loose rust you can, then paint the Rust Coverter type of clear thin liquid, paint it on and let it dry 24 hours. The phosphoric acid converts the rust to an inert black material. Then top coat with one of the rustproofers.. You can get them in a spray can, for preventatively doing this (Rustproofing your truck) before you get any rust. The spray goes on inside kick panels, doors, tailgates, the kinds of places the rust would start. NOTE, rust out comes from the INSIDE... That is where you want to spray particularly if you are in a rust area where they lay it on black ice on the roads, or like for us driving on the beach. We rust proof our trucks when they are brand new..!!
