If you like paste wax, I suggest you try
Blitz Wax. Same family run company has been making it since the 50's. Easy on and off

. Outstanding depth and clarity. I use it on my antique cars.
I've been using Zaino on the MINI lately, but a combination of Blitz and their Omega Glaze is tough to beat - especially on a dark colored car. I have a '35 Packard that has the original black lacquer paint (from 1935). It has, I don't know how many coats of Blitz on it. People say it looks like a brand new car.
OG's website looks like a 12 year old put it together; ignore the amateur appearance. Call and talk to John or Rick (800.782.3329), brothers that have been in the family biz since they were in diapers (or maybe even before). Tell 'em I said to call - it may even get you a discount.
They used to keep all sorts of competitor's products around to do comparisons. They may even have an ancient can of Classic Car Wax in the back room.
(disclaimer: I have no interest in One Grand, other than being a customer for going on 30 years)
