76 Olds...
Dean,
I only offer Zaino as an option for specific customers (higher end vehicles, classic cars, etc) And I charge a little more for it (ok, a lot more).
Incidentally, I'm not a "Zaino" fanatic. Sure, I really like the stuff - and think it is extremely durable, but I don't use it exclusively.
Having said that - let me add that I also don't adhere strictly to the "Zaino Rules of Order"... I've found Z1 and (most recently) ZFX to be a bunch of hype. I've put multiple coats on cars with a "curing" time of about 20-30 minutes per coat WITHOUT an accelerator like ZFX. The secret is low humidity and heat. By the way, I work in a location that ranges from 2500-3500 feet above sea level in the mountains, thus low humidity AND high heat is the norm for this area.
The only Collinite product I use regularly is #845 Insulator Wax. I've been using it since 1988, and still love it! I buy bottles of it by the case directly from Collinite Corporation. If you ever get the opportunity, try topping AIO with Collinite... Wow!
This particular wax continues to bead well after 8 weeks on daily driven vehicles. Goes on quick and easy off. Add to this the fact that it won't stain trim - and it's easy to see why I love it... (Oh did I mention it's great as a marine wax too?)
Btw, Thanks for the compliment regarding the Olds...
