Hehe... just wait, the Zaino Zealots will flock this post, just give 'em time.
I've bought a few Zaino products: Z16 tire dressing, Z9 & Z10 Leather Cleaner & Conditioner, and the Z18 clay bar.
The Z16 and Z10 are awesome products.
I haven't tried any of their 'paint' products, and don't really plan to. Why..? I don't need to. Too many wonderful alternatives out there.
