Before I discovered this great site, I made the mistake of using microfiber cloths sold at Target. This plus bad technique have left my car with faint scratches that can be seen under certain lighting, especially in parking lots. I plan on using 3 coats of Z5 followed by 2 of Z2. The car is silver. Has anyone had any success with Z5 and scratch removal? I know Zaino just came out with their own scratch removal product, but that is a last resort type of product. I don't need that.
