The clay worked okay and got the surface clean, but did no "repairing". I was not happy with the cleaner and the shield I think did absolutely nothing. I applied it several ways trying to make it work, but it definately did not hide pits nor did it bead water miraculously. I took pictures a while back and you could not tell which side had the Shield and which didn't.
Again the clay did work and cleaned off hard water spots, but the other 2 products in the kit did nothing for me.
