I had the opportunity to test at the weekend that Petzoldt clay bar by a colleague.
And I'm super excited, so I order me directly here.
A precondition is the proper use of clay, what some of the fail here recessions Post apparently already.
The usual mashed flies and insect remains on the bumper for me are still a major problem.
Mostly I already lean his whole body against the car to you (each spot individually) with a cloth to rub off.
This makes after half an hour not only no fun anymore, but eventually also lacks the power and motivation to keep going.
With the dough I instead comfortably sat down front of the car, sprayed with a spray bottle clear water and went to the dough quite loose several times over the spots. Lo and behold, without effort or circumstances disappear all stains.
I was really surprised, because I was indeed already been described to me as a little "magic bullet" but am always a bit skeptical at something.
From now on this clay comes in every wash my little used.
An absolute must for every tuner pays attention to the smallest spots or the normal user is dear to his car.
Thank you for this brilliant stuff!
