Okay so the truck I ordered is at the dealer lot and was told to pick up for April 1st to see if any new promotions will happen.

See below:



What should be my next steps? Document it and open a case file with Ford or just take it as “surface rust” and carry on with life?

Much appreciated. Thanks

Document with close up photos. Date, and time of photos taken, open case with Ford for sure.

After taking pics of several new trucks rust on a couple lots, researching options, reading posts, discussions with my dealer, local Line-X, Rhino Linings reps and my buddy that lives in snow, about rust, painting, undercoating, etc I agreed to just get this $39.99 pack of fluid film off Amazon, and spray it myself once it arrives. In San Diego/SoCal its usually a non issue, so I'll take what I get, clean it up, spray it down and see how it goes. Will try n post pics etc once it arrives.

You planning on throwing a quick coat of paint on prior if there is small spots of rust? Or just put this right on

The fluid film is great stuff but has a weird smell.

You can put Fluid Film on first and that will stop the rust but then if you want to paint it later you’ll have to remove the Fluid Film. To remove the Fluid Film you have to spray it with Simple Green and spray it off with water.
I think the best thing to do is use Rustoleum Rust Dissolver and then paint it with High Heat paint. Then if you want, you can spray with Fluid Film.

Yesterday I spent about an hour on mine taping and spraying. Was not bad but thought I should get ahead of it. I used Dupli-color Rust Barrier on what I could paint and SP-400 on the non painted stuff. Definitely looks better. Not sure what to do about the unpainted areas near the rear hub. Will tackle that another day.

I was on the fence about painting. Maybe just the diff and axle housings since they are the biggest problem area. Prep and paint
Particularly after seeing some really nice spay jobs on here.
Looking at Rustoleum, etc

Then I can use fluid film with the hose nozzle to hit the inside of frame rails and non painted parts at the hub and front axles that seem to get rusty. Should help out in the long run, as I plan to be buried in this truck, in 20-30 years LOL

My dealership addressed the issue for someone else on this forum. If mine comes in rusted, I will have them remove it and repaint the effected areas. Then I will fluid film the bottom.

Is fluid film effective for the exhaust? That is my biggest worry for corrosion.

Yes Rust, you all saw the pictures. But, Wow, this truck is amazing, the powerboost, 3.5, stereo, seats, the truck is awesome.

when I get back from a trip next week, I have a few issues:

1. int. lights don’t work, others had the same. I guess they know how to fix the short.
2. funny, pain on body had a few scuffs, dealer will fix but not the rust.
3. some kind of padding between the cab and bed, one side is leaking off

This truck is so much better than the Chevy Trail Boss, GMC AT4, or the Dodge. Forget Nissan & Toyota

I like seeing the American Flag as I enter the truck.

Finally received my truck and it was a pleasure. The dealer was very cooperative and actually submitted a claim against Ford to take care of rust. I only had moderate rust but I emphasized I wouldn't accept unless it was cleaned and a nickel chromate primer was applied. It didn't pass my first inspection so they performed an additional coating in all the critical areas. Muffler had some rust but spent about 2 minutes with steel wool pad and most of rust was gone, I really don't think it will be an issue in my zip code (AZ). It was nice doing business with a smaller dealer who was customer focused and valued my vehicle like it was their own. A few pictures after coating was applied, it can be done if they want your business. I'm grateful to this forum who brought this issue to my attention and very disappointed in Ford's position on those receiving a raw deal.

Not sure if one should put anything on the exhaust system do to the high temperature.
