Cement On Porsche Need Professional Help

On my way home from work Friday, the SUV in front of me hits this huge puddle of crud in the road and splashes it all over my car. I figured it was time for a good wash anyway, so when I got home, I gathered up my supplies and started the process.

As I am drying off the car, I notice that some of the crud did not wash off ( I am assuming that cement was mixed in with the mud and gunk ! ). I got out my orbital polisher and Z5 and did the best that I could but I was still not able to remove all the remnants from the paint...

I took a look on autopia and they suggested distilled vinegar or this stuff :

Does anyone have any experience with this product ? Will distilled vinegar hurt the paint ?

Any suggestions from all you detailing gurus, or should I take it somewhere and have a professional take a look ?

Thanks,

Nick

Muriatic acid will take it off and won't harm the paint accord to "Click and Clack" on CarTalk.com It was the subject of a call that I think you can still find on their web site. They actually checked back with the guy and he confirmed it worked fine. Here's a link: http://www.cartalk.com/ct/review/show.jsp?showid=200715

Please confirm that yourself before you try it at home. I'd hate to be responsible for destroying your paint.

Good luck

The vinegar should not hurt the paint, it is a common solution for helping to remove water spots too. Try to re-hydrate the spots if you can by leaving a wet wash cloth on them for a while.

I do not think it was actually concrete, one of the under layers of a road is this very fine grit, grayish material that when mixed with water does stick and harden like concrete. Had this happen to me a few months back when the road leading to my house was being redone.

I ended up washing the car multiple times, gently scubing the affected areas, then used a clay bar to remove what remained. If I had a pressure washer I probably would have (cautiously) employed that too.

You will want to apply your favorite wax product when your done though.
