Here's another one of those classic example how advertising plays to something which is present in any way or entry. The reported effects were made with repeated attempts at various vehicles and surfaces. Not the promised splendor but a smeared surface was the result. Even the plastic cleaner did not bring the desired result. From the perfect shine as promised in advertising, the result was as far away as the debt freedom of Greece. The roll-off effect I have not even tested because I should be clear that time is too precious, and the result. CONCLUSION: I can not give buy rating. Goods not keep what is promised in the advertising. The word comes to a rip-off as ever in the Sinn.Es are care products on the market that can be used with much less effort and a much higher effect than this product.
