As far as I know none of the ford vehicles come from the factory with any rust protection.

Wrong.

The entire shell of any automobile today is usually dipped in a zinc bath along with other chemicals which treats the entire body and all crevices of the body. That dip process is what protects the metal from corrosion. After it goes through the "dip", it then goes through the priming/sealing stages where either robotics or line workers will apply the body seam fillers to where ever it's needed on the vehicle. After that is paint stage, etc.

Ever seen the video "How a Car is Built - 1994 Mustang"? I have the original full length DVD packed away - but here ya go if you guys have not ever seen it - it's really cool.

Check it out here:


The build processes used then in 94 are most likely very similar for today's S550 Mustangs (and other Ford Product Lines). I'm sure someone can collaborate if the steps in that video are different or maybe updates have occurred to better the processes too.

As far as I know - if the reference to "rust proofing" IS asking about the actual rubberized undercoating applied to the underside of a vehicle's floor pans - I don't know of any Ford vehicle that comes out of the factory with such an application.

Believe it or not - "undercoating" can be more detrimental to a vehicle than if there were no "after" applied coating at all. If the undercoating is not applied correctly OR if there was trapped moisture anywhere within the crevices or areas that undercoating cannot get to - the undercoating once applied traps that moisture. If the undercoating is not applied correctly, moisture can also get in between it and the metal it's trying to protect. Over time that's going to cause big issues such as rust, rot, corrosion etc.

Many vehicle manufacturers won't apply it.

You know what will protect the underside of any vehicle and engine components from corrosion? WD40. Many think "WD" is just a lubricant - it's not just a lube, it's original use was for "water displacement". WD40 has a new product out now called "Long Term Rust Inhibitor", which will protect metal up to 1 year. They also have other products that are water resistant. I've used WD40 on prior Mustangs I've owned without ever an issue. It will also stop that ugly aluminum galvanisation or chalky white corrosion - just spray it on such parts, let it soak in and that's it.

I personally would never use any undercoating on any vehicle - it causes more damage than good.

Also - never park vehicles on lawns, or dirt surfaces for long periods of time - morning dew, rain and weather variances cause moisture to saturate all suspension components and the underside of the vehicle - which leads to rusting.

Hope the above helped someone!

I was talking about the undercoating that the OP was asking about. That process above has since been replaced AFAIK, due to newer metals being more corrosion resistant. Metals are not dipped in our plant so it would have to occur before it reaches ford. Not sure about cars being coated in Europe. Ford hasn't had rust issues since the early 2000s anyway so Im pretty sure the metals is what has changed.

Tell that to people who live in Michigan!

I live in Germany but have been to Michigan Illionies where REO Speedwagon come here !​

I'll agree 100% to this statement. I remember back in the late '70's and early '80's when Ziebart Rustprooing was the big thing for everyone to do to their new cars. I cannot tell you how many cars I was repairing total rust out that had those little yellow "Ziebart" plugs in the frame rails and rockers.
Not sure of their quality today (Yes, I Googled them and they are still in business) but back abut 35 years ago the saying in the bodyshop was "Want guaranteed rust and rot? go Ziebart!"

That was Chrysler. Remember the video that went viral of Chrysler employees smoking weed in the parking lot during lunch break?

Very nice write up.

The dip is called ECoat. Electricity is used to adhere the ECoat to the bare cleaned metal. Then Sealer for the seams, Primer, Basecoat and clear coat.

I saw a picture of a guys spare tire holder in the trunk, and it looked like ECoat only. It is gray in color. It seals every nook and cranny.
