Undercoating

Almost any spray rubberized undercoating is good to protect the pans.

However, you have to treat the surface first. Don't just "brush" the rust off. The corrosion will continue, encapsulated in the undercoating, eventually eating all the metal away.

Clean it to bare metal, and treat with POR15.

Or at a minimum use a product such as "Rust Mort" to neutralize any rust.

Anybody try Rhino Liner yet????

I like POR-15 a lot too. Just recently I started using zero-rust with their phospate pre-treat. Really liking that and about 1/3 the price of POR-15.

Correction: Don't clean to bare metal! You don't want a shiny surface. Follow the directions.

By "Clean to bare metal" I meant take off any flaking paint, under coating or rust. Down to the metal. Not necessarily to "near white" metal. (A MILSPEC term)

I plan to use pick up truck bed liner for undercoating. The spray is easy to work with. POR 15 requires a lot of prep like rinsing it off the metal ready with water. I also plan to use a wire brush attachment on a drill to remove the rust and then wipe it all down with wax and grease remover.

If you had a part sandblasted, what would be the correct way to follow it up? I have to do something about a trailer hitch soon.
