Rusty Aussie mach 1 mustangs

[Basspro302]

That’s interesting all out mustangs have a bit of black rust proofing splashed around under the car , don’t yours ?

No they are already rust proofed, those black rubberized coatings are the worst they hold moisture and salt against the metal.

My old 2013 had 115k miles of michigan winters and didn’t look anything like that.
The amount of corrosion on the differential is suspicious. Thats not typical if pulled aluminum diffs at the junk yard that didn’t look like that lol.

Why skeptical ? Black paint is some sort of thick coating and on all our Aussie mustangs . I never knew yours did not have it till now . Both of my S550 had it and even over sprayed on the back of my wheels . It seems to be just hit and miss when they do it .

Hi, You are so right l bought a Bullitt & this was sprayed with black paint all over the inside of the wheel rims which took a lot of time getting it off plus all over hit & miss on under body.

6 winters in Chicago on my 15GT and it didn't look that bad. I always washed it but still.
IMO, this is from the ocean air on a rusty cargo ship. Salt saturating the air.
I feel really bad for those with this issue as you really don't know how deep the corrosion is as this is only what you can see.
Special car that Ford tried to get to the land down under and failed miserably in so many ways.
I'd walk if they pulled all this shit on me.

Doesn't Ford use the type of coating that BMW used to use when shipping vehicles overseas?

Doesn't matter if the car was not exposed directly to salt as in splashed with it, it's exposed to ocean air which carries salt in the misting. Doesn't take that much for salt mist to start materializing as rust on any metal parts that is bare or uncoated.

That black undercoating is trouble. As mentioned above, if the undercoating did not cover all crevices, nooks or spaces in between metal to metal parts, all it takes is moisture to breach those areas and it will accumulate above and within the backside of the undercoating.... over time, that's going to be cancer.

I don't know why Ford is electing to have any S550 sprayed with that undercoating... sure it may prevent some corrosion, but long term affect if the vehicle is exposed to daily driving in harsh climates will be problematic.

Why not just coat the underside and engine bays with WD40 prior to overseas transport? That would stop any potential corrosion from the over the ocean travel - and can be easily washed off once offloaded to a dealership. Also, no it won't harm painted surfaces NOR will it harm anything if the engine is started with it on it...

It's a better solution than black rubberized undercoating or lack of it...

U.K. owner here.

We get the black coating. It’s poorly applied and very variable from car to car. The only thing you can guarantee is that they will get some on your rear wheels and also on the bodywork.

Fortunately it’s not the particularly rubberised stuff, it’s more like thick paint.

They also cavity wax various areas under the car and also inside the doors - the later are still weeping on a warmer day.

The black stuff comes off with thinners (I had to do my tail pipes) and clay will bring it off the bodywork - I even had it on the flat tops of the rear fenders / tops of the door handles / bottom lip of the gas cap recess etc …

If I had the option, I would have taken the car without it and sorted it myself, properly, with a quality product …

Is that "wax" the product that BMW used to do - and once it reached the dealers they were to power wash it off the engine bay and under the car? Like a clear type of product?

 

[WD Pro]

No, I know the stuff you mean on the old BMW’s, but the name escapes me.

This is the cavity wax that they inject into the doors (as pictured) and the box sections under the car :

The white tape on the bottom of the doors covers the drains / holds it in place / stops it dripping during shipping :

That looks like fluid film, thats good stuff. Do you have pics of the underbody on uk cars?

I'll try to take some photos under my car when I get a minute, but when I looked underneath after picking it up a few weeks ago, it also had some white spotting all over the underside which worries me now after reading this thread.
And to confirm, the black crap is sprayed all over the underside of export cars (mine included)
I also bought a second hand set of factory wheels last week and they have overspray all over the inside of the rears too.

Can someone confirm, when these are shipped do they just sit on an open deck?
My car came with the shipping document which shows a comment "Snow & Salt spray" .
Not sure if that's what they call the stuff sprayed on, or if that was a comment on the condition of the car when it was loaded.
It was pretty dirty when I picked it up but being a dark colour it looked ok under the dealership lights.
It wasn't until I got it home in the sunlight that I saw how many dirty water stains were all over the grille, rear end, all over the car in fact - which is why I thought it had been exposed to the sea for a period of time.

Why would they spray the exhaust tho?

Because someone at Ford isnot doing their job and following up.
Thing is most owners are unhappy about it, but being Ford, it will never change.
As much as I like my mustang, I doubt I’ll ever buy such a poor quality car again.
It’s been a frustration from the day I got it. I have to constantly tell myself it’s a Ford and to just accept it.

Ford’s metallurgy group needs restructure. After all the failed 2015+ mustang and F150 AC repairs that cost a fortune….

For ocean shipping, Ford needs to consider tried n true industry standards.
Or at least run the cars thru undercarriage wash w cosmoline carrier/VPCI/buffered phosphorus.
This can prolly be done aqeous base if needed.
like $2-4 car plus cost of car wash end of line for export cars.

I apologize on this. I didn't know they would paint the bottom black as it made no sense to me. Most of the suspension bolts are stainless as is the exhaust. Painting it would just cause a hazard burning off. It looks like a salvage car that was flood damaged to me. Like a hack job.

It's not paint, it is an under carriage rust protection seal almost like bitumen. It is sticky and very very difficult to remove.

It is almost a must for cars driven in places where all four seasons take place and where salt is used. All cars in Sweden do get a treatment of some sort before being delivered to the dealers.

it depends on where the job is done, usually it is done once the cars delivered to the harbour, the folks blasting the stuff on can be more or less precise/do/don't know which parts to treat and you can have a mess.

On my GT I had overspray in the barrels of all four wheels, but the exhuast was untouched, the springs had overspray, on them and so on ..... I still have marks on my garage floor and my tools are all messed up as the stuff doesn't come off more or less...

Not directly sorry. Other than overspray, the black crap is mostly aimed around the centre of the car spreading wider towards the back end. You can see it a little on here (diff / exhaust pipes / silencers - but none (other than overspray) on the rear suspension arms :

'In general' the front, sides and suspension are clear, you can see on this photo when I fitted my jacking rails there is nothing on the sills / pinch welds :

Beg to differ, its a single pack black paint. It comes off with acetone. Any activated paint does not come off with acetone. Once its baked on exhaust, acetone wont really soften it.
Definitely not sticky .
Perhaps Ford Sweden applied the sticky bitumen you refer to ?
Bottom line, if you want to seal the bottom of a car, it takes a lot of work. Like you said, depends who does it.
What Ford does is just useless.
