What is this and how to stop it!?!?

trek,

I uploaded the below two pictures into your gallery here,

This one looks like an adhesion problem between the primer and the steel

I was thinking the same thing. Since on black cars it goes Primer, Base Coat(white), then clear coat, this looks like it is peeling from the metal up. The metal should have a almost painted gray tint to it, from where it was primed before painting. If it doesnt, and it just looks and feel's like metal then when the hood was redone, it was done incorrectly.

Could the vehicle have been repainted?
Maybe just the hood has been refinished.
Anyway, stripping and refinishing the hood would be my first step and hope the rest of the vehicle's paint doesn't do the same thing.

I purchased the car from the original owner who was a Manager at a Range Rover / BMW Dealership. It was a showcase car, then he bought it from the dealer. He said it was garaged its whole life until 3 or 4 months before I bought it because he upgraded to a '08 528. I unfortunatly do not have covered storage so it has been battling the elements since I've owned it.

He made no mention of it being repainted.

This one looks like either de-lamination or clearcoat failure



Regardless of the problem and the root cause, there's nothing you can pour out of a bottle that will fix the problem.

Using a can of spray paint you might be able to somehow patch the problem but using a can of spray can paint and making it look good will be a challenge. Also if the root cause is a surface adhesion problem between the metal and the primer coating then the problem will likely continue wherever there's surface adhesion issues below the color coat.

I uploaded all the photo's with original resolution into the gallery so if you want you can deleted the ones you did.

Could just be a prep problem or a paint quality issue from the factory.


Don't feel too bad about not having covered parking, my truck sits outside all of the time too as it won't fit in most garages. I don't have a painted roof but I do try to keep a good coating of the RaggTopp Fabric Protectant on the Bikini Top and keep the paint polished and waxed often as well as dress the tires often too.

My truck's paint is actually a single stage finish so if I don't keep up on polishing and waxing it will oxidize.

The larger images help to better see the problem...

I deleted the little 288 pixel wide photos...

Uploading images to the gallery and then inserting them is such a better way to share photos versus simply attaching them. It's a good idea to resize them to about 600, 700 or even 800 pixels wide first just to be a good steward with the AG resources.

Cropping the fluff is also helpful as it keeps the focus on the subject.

Just added 35 photos here, all the pics in post #16 and #17 were cropped and then resized to 700 pixels wide.

Yep it looks like poor prep work. It looks like the primer did not adhere to the metal, and the base coat did not hold to the primer. So probably either incorrect primer or the etching properties of it, where mixed wrong.

this was not there this morning when I left for work, but with the torrential downpour today it was there after lunch

Hey Trek,

What does the car fax show? It will verify how many owners etc. Also, if there has been any insurance work etc done on it. My account expired on the 23rd or I'd pull it for you.

Also, if they did a bad job, chances are if you pop the hood and truck etc, you may find tape lines. Check under the hood for signs of things being moved. Especially look close at the washers where something was taken off and put back on.

Anyway, it's kind of irrelevant but would be nice to know if the persons were up front with you because it they repainted a car then makes you wonder why and if there was more than 25% damage. Here, that is supposed to be disclosed during a title transfer if it wasn't somebody committed fraud. But if a manager of a car dealership told you he purchased it directly from a dealer and is the only owner, may be worth doing a little investigating.

Actually, if you find out something has been done and can find out who did the work. Hopefully you can verify what they did. If they just did the hood and trunk, that may not be too expensive to have the clear coat sanded off and re clear coated.

Good Luck

You'll never believe this...my pal down the street has a black BMW convertible the same year as yours. He's had it for years and takes very good care of it. About six months ago it started to do the exact same thing. I referred him to an auto paint specialist. Mr. Phillips is right to the letter. Diagnosis was "failure of adhesion between the primer and the steel".

Did carfax before I purchased it. The carfax shows 1 owner guarantee. Owner says he was a manager at a Range Rover/BMW stealership and the car was a demo car. He was an older gentlemen who seemed believable. It was garage kept untill i purchased it, and now its outside 24/7

What route did he take? If its still unfixed would you mind snapping a few photos?

Full strip and respray...there was nothing else that could be done. He might be home today I'll see if I can snap a few pics.

Yea i didn't think there was anything else that could be done. Also if he wouldnt mind saying how much he spent on it?

I'll ask him...I think it was about $3000 by the time it was all said and done.

Some manufacturers have warranties on paint failure like this, but typically only cover the first 7 to 10 years. But if it were covered, the BMW dealership would have to repaint the entire car.

It almost looks like the car was vandalized (and thus a re-paint would be covered by your comprehensive insurance and your deductible should not change) by pouring something over the car causing the bubbling. I know pouring brake fluid over paint causes catastrophic paint failure similar to this where the paint comes off the base metal.

Good luck!

Really. Hmm, I have a beat up black Mercedes door that I'm done with. I may go out and try that before I throw it away. How long does it take to see the effects? I need to get it out of the garage before too long but I'd be glad to test this and post pix if the process doesn't take too long.

Usually what I see when brake fluid gets on to light colored single stage paint is it will stain it a blueish grayish color.

I can't remember seeing brake fluid spilled on a clear coat finish?

It's nasty stuff so anything could happen. It looks oily but if you get it on your hands it doesn't feel oily but instead just icky. Always wear gloves when working with brake fluid and eye protection.
