[b][ I have used the product since Batman first painted my car in 2006.
He suggested it as it was the only product that he knew that (didn't) leave a residue. I use the Z 6 almost everytime I bring the car home after a long drive. I use the Z2 for filling in the minor scratches and the Z5 for a gloss shine. THen, if I still have hands left......I use the Z6 over top. It is a 4 year old car...and honest to God....it looks NEW!! I never use water to clean unless absolutely needed.....which has been 3 times in 4 years. It is amazing how it never builds up. So, there is my facts that may help you. There are a lot of good products out there. Zaino is just so easy to use, gives the greatest shine and not expensive.
BTW....my car is dark silver with a black stripe.
Hope it helps...........
