Some weird stain on a friends brand new car

Wow, I would be pissed.



I would have guessed tar caused that because I have two very small spots on my front left fender where tar that had sat for too long (several months...shoot me!) stained the paint. Nothing has removed it.



How many days/weeks has he had the car?
 
Not sure, he said recently. He said it wasn't like that when he bought it, so I am assuming he got soemthing perhaps flung up on it.
 
I had some success with P21S Total Wash on a similar stain in a similar area...it had only been there for a few weeks though. The paint is fine, but it will remove any LSP you have.
 
from the title of the thread I figured the stain was on the seat from a "very happy new car owner"... but anyways..LOL I guess you'd have to wash with dawn, and then try something a little more harsh like westleys tire cleaner, or some denatured alcohol. Try some things that are harsh but within limits that won't soften the paint, and of course do it by hand in a small spot until you figure out what works.



I'm guessing it is an oil base, and soaked into the paint or clear coat and will need to be wet sanded if nothing else works.



believe it or not, a few months back our entire flightline of flight school airplanes was covered in overspray from blacktop they were spraying on the taxiway. It had dried in the hot florida sun for 2 weeks at least before they attempted to send someone out to remove it. The detailing guy who removed the blacktop spray from our airplanes ended up using MEK. I was worried that it would soften the paint and cause it to fall off after a while, but it worked out great, he did it in direct sunlight, the blacktop wiped off easily, and the paint was fine. nothing else would remove it, and our alternative was to repaint every plane.
 
That looks very similar to what is referred to as "photo-spotting", and it can be caused by the petroleum distillates and other chemicals in some of the (solvent-based) tire shine products, combining with carbon black that's in the tires. It's of course possible he ran over something that resembled this chemical soup too.



A few of the car manufacturers have released TSB's about tire dressing stains for this reason. I've seen customer's cars with it that couldn't be repaired by any known detailing means. Sometimes you can get lucky if it's fresh enough.



Which leads to the possible bad news; Often, the panel must be repainted due to the permeating of the chemicals down into the clear. Best of luck though. :)



P.S. That's a good place on any car to apply some Xpel or Stongard etc. Something sacrificial to save the paint in such cases.
 
go back and demand a brand new 05 be ordered identical to the one he bought, and do an outright exchange... but be sure the dealer doesn't touch the new one when it comes in.



And yes, I'm dead serious.
 
It just doesn't look like sling to me. I've had sling, and it's always, well, looked 'slingy'. A definite pattern where you can tell the direction it came from. That looks too random, and the spots too round-I would expect comet shaped spots. Perhaps Dr. Henry Lee could investigate.

Are the spots definitely 'on' the paint? I'm wondering if it's a paint defect, or even something like the dealer touched it up before delivery & there was contamination?

That is pretty much what I was thinking since clay and AIO didn't get it out, I figure it probably penetrated into the clear.
 
~One manâ€â„¢s opinion / observations~



Aerodynamic spoilers, wings and lower valances are polymerized; this technology incorporates the ethylene-propylene rubber on a molecular level, to give an excellent balance of key properties such as impact strength and stiffness. The paint used usually contains an elastimeric additive (flex agents), which is similar to microscopic open cell foam to ensure its flexibility is maintained and to prevent `spider web' stress cracking. If â€Ëœslingâ€â„¢ gets into these â€Ëœpocketsâ€â„¢ they penetrate the material and you will often be unable to clean them.



~Hope this helps~
