I’ve lost all confidence in Ford and the dealership concerning the rust. I don’t want the rust to just be covered up. So, I fixed it myself and did the job correctly.

I really like the looks of this and will probably follow the same procedure. I am curious though, why not just spray with Rustoleum rust converter? I know that seems like the lazy man's way of doing it, I'm just curious why this wouldn't be much easier.

Because Rustoleum rust converter just doesn’t have the horsepower to convert that much rust.

Also when the truck was cold - applies a light coat to the exhuast then cleaned it with #003 &0001 steel wool pads. Came out all nice , clean & shiny as like they should be.

I'll never understand how anyone could pay $XX,XXX.00 for a brand new truck, WAIT an eternity to get it and just blow off the fact that the undercarriage looks like it came from an old junk yard.

If my truck shows up like that there is NO WAY I'm taking delivery until the dealer REPLACES (not cleans) the rusted parts.

I think people might confuse Rustoleum rust converter with Rustoleum rust Dissolver. The rust converter is a paint and the rust dissolver is a rust remover. I’d suggest reading the Rustoleum website as it is too much to type out here.

There is no way a dealership will replace an axle and surrounding parts. As I mentioned in the first post, I negotiated an additional $200.00 off before taking delivery to cover the cost of undercoating. I obviously addressed the rust issue myself but I still plan on getting the entire undercarriage rustproofed.

I think your options are to negotiate more money off, insist the dealership remove the rust or just refuse to take delivery – which might cost you your deposit. Personally I wouldn’t trust the dealer to do a good job so you would be better off doing it yourself or take the truck to a rustproofer and have them do a descaling / rust removal before spraying the undercarriage.

I'd be careful spraying any type of rust converter or dissolver around under the truck without being very careful what it touches. Most of these products are acid based and work great on iron parts that are rusted but I'm not so sure how compatible they are on brake lines, wiring harnesses or fuel lines.

Or find another dealer and order a 2022.

There is NO WAY I'm paying $50k+ for a rusted POS.

NOT A CHANCE!

"Rust never sleeps" isn't just the name of a Neil Young album.

Regardless... if they think you'd be willing to take delivery of something like that, they KNOW you won't do anything about it when the rust starts seeping through the pretty paint in a couple years.

If your hood looked like that, you wouldn't take $200.00 (or whatever) off the price and go repaint it. And the hood has absolutely no effect on how your truck operates no matter how rusty it is. I've seen pictures of some very important components like Brake Calipers and mufflers rusted to hell.

Sure the 3rd member isn't likely to rust through to the point of failure but it's a clear indication that it wasn't properly manufactured in the first place and makes you wonder what other aspect of the manufacturing process was shoddy.

You're likely right that the dealer isn't going to replace my entire rear end or maybe even my exhaust system and that's fine. He can find some other sucker to buy it.

Were I in a big hurry, I'd be driving a brand new white V6 XL 4x4 with roll up windows and an AM radio right now for $30K less.

I'm not and I'm not.

I did the same. Didn’t take long. Mine wasn’t too bad so I used a rotating wire brush. Probably faster for me than getting it done at the dealer.
