Query: Great restoring product

I used this on my girlfriends 12 year old Solara, and it really did the job. Her car was very rough to the touch, and after using this clay bar, it made it much smoother (almost like it had been waxed). Make sure after using this clay bar to wax your car after. The car now looks 100x better than it did before.
