After a wash/clay, try the Z AIO first to see if you really need to correct heavier marring.
ZAIO is like using P21S Paintwork Cleanser only with Zaino sealant added to it. Nice and mild enough for simple cleanup.
Follow with a Z-CS application and you're good for a long time.
Whichever way, wait for the sealant(s) to cure before you wipe down with Z8 for a stunning shine and depth.
I'm still playng with different ways to obtain that multi-Zaino look with very little effort for other Porsche owners who are just "wax on, wax off kind of guys and don't want to spend countless time to do a full Zaino sealant treatment.
So far it looks like ZAIO/ZCS theme for now with Z6 and Z8 after cure time. Porsche paint being so damn soft it doesn't take much to correct it, and if it's really light, ZAIO may do it, if not, ZPC. If this still doesn't clear the defects, then it's off to a qualified deatiler for those owners.
Just with anything new you try. Manage your time accordingly. Too many new users have to rush at the end as they run out out of time starting something new or rush to beat the weather. Take your time, get comfortable with Zaino to get the best effect and you'll end up cutting the time as you hone your application skils with Zaino or any product.
Keep us posted!
