This stuff made my first use of a clay-bar a breeze. Just be sure to watch a few pros at work on you-tube or similer before you undertake such a critical process. I urge you to believe every review which concludes that clay-bar treatment works. You will be able to check your tie from distance outside your car.
Product is not only easy to use, but the instructions are accurate. The lubricant does its job, and seems to be very user friendly for both the car and myself. Have used the prodcut several times now and its simply awesome.
