After I have tried many polishes, I changed a few years ago about the products of Dr. Wack and have never regretted this step. The processing is compared with the products from the super respectively. DIY much easier and the result is impressive. A strong verkratztes- or weathered car you will can not do up with this polish, but this polish is not "sharp" enough. For a reasonably well maintained car but this polish is my first choice and I've tried a lot of expensive products from abroad. Easy to apply and applied in the correct order with a super result. Dr.Wack has I highly recommend!
