I just finished re-applying Zaino for the first time this season. I had about 5 coats of Z-2 on from last winter so, thought I would start fresh. Frankly, the old stuff still looked great but, its a long weekend so thought "What the hell". First I washed with Z-7 (2 caps) and one cap of dawn. Then clay barred with Z-7 as lubricant. While I'm sure it did make some difference, it was almost a waste of time. When using the clay bar I didn't feel any drag as you do when the bar is doing its thing. Felt smooth when I started, and smooth when I was done.
Next, 2 coats of Z-5... worked great, same as when I last used it in the fall of 04. Now its time to mix the Z-2 Pro. Right away I noticed the Z-2 had an oily feel and was thicker than I remembered. Rather than using the cotton pad that came with the kit, I remembered BradB's post awhile back saying he liked the foam pads for applying zaino so, I was using the foam pad for the first time. The Z-2 went on easy but, with the old stuff, the trick was to use so little on the cotton pad that you had a hard time telling where you stopped. With the new Z-2Pro, it left a light film that was actually helpful in seeing where you had been. I tried to use less and less but, the foam pad did such a good job that you could still see that faint film. At first, I wasn't sure if this was do to using the foam pad or the new formulation of the Z-2 Pro.
Removal was as easy as ever. NO RESIDUE NO CHALKING and a deep wet look. I did two coats today. Think tomorrow I hit it with a quick Z-6 then another coat (or two

) of Z-2 Pro.
Bottom line... I like the Z-2 Pro better than the old Z-2. Actually easier to apply, just as easy to remove and no residue

BTW: You'll not beable to rinse the bottle with only hot water anymore. The new Z-2 Pro doesn't seem to be water soluble. I had to use Dawn to clean out the bottle and foam applicator.
