Fat chance!
Really even ask Sal Zaino!! Z5.. It's only really for very light cobwebs. It's not a glaze like a 3M or VM which has clay to fill the scratches. That's what most glazes do is fill. Some do some don't. Just like Zaino, don't think it's polish because it says so, it's not. Same for Glaze, some are true glaze, some just use the word "Glaze" as in "Polish" you get the idea...
Zaino requires the most absolutely swirl, scratch-free finish for the best effect. Remember, this is "Show Car Polish" Show Cars are mostly pampered and have no swirls as well as being setup under high intensity lighting (indoor events) and this is where Zaino stands out in shows.
It's been said so many times before... develop your finish so that it is defect free, THEN try Zaino.
When you've had enough, there are several good sealants to try that are easy. Wolfgang, Poorboy's EX and EX-P, Klasse etc.
I'm sure, give it time, this thread will also start the Zaino wars once again. I used Zaino, still have it, nothing wrong with it, just there are easier ways of getting there.
