Once you apply the first coat of Zaino AIO as the base layer...then top it with Z2 Pro....what's the upkeep after that? Do you simply apply more layers of Z2 Pro as needed? Or every so often do you need to strip everything off and reapply AIO and then Z2 Pro?

 

well thats a very good question that goes with all sealants/waxes IMO...

i still haven't tried zaino, though i do look forward to it. as with other sealants, over time the zaino will break-down, and naturally will need more applied for continued protection. how often u apply AIO will be up to you, but i'd think you can just keep layering Z2 if u apply often enough. On the other hand, if you really stretch it to the 6 month mark, I'd say go with the AIO followed by Z2 all over again. So it's a matter of upkeep. No matter what, I can't see a need for AIO to be used more than 3 times a year

 

and then there us wacko wackos...
over 30 coats of zaino with who knows how many layers of p21s and lusso oro last time mine got removed. my removals are by clay and polish.
almost every time that the car gets washed it gets zainoed or waxed, depending mainly on my mood!!
in between it usually sees a carnauba based detail spray.

 

^ WOW! now THATS hardcore! right earned your "chief wacko" title
