Thank you for your Tech Shine system. My Ferrari has never had any expensive five-year wax or sealant process. I have my favorite detail shop hand wash and apply Tech Shine every few months. My detailer loves the swirl-free washing sponge and most of all, the better than new finish that Tech Shine creates in just a few minutes. . My friends just assume that I am always waxing my car. You cannot go wrong with this product.
