What is your favorite Spray on Wax??

[SameGuy]

It's also one of those products that crosses the boundary between hobbyist use and professional detailer use. A hobbyist can find many ways to use it well for his or her needs, while a pro can use it for quick turnarounds on production jobs or used car dealer contracts.

...I've heard D156 is nearly identical to U Quick Wax?

You heard correctly.

Megs D156 - Very easy to use, helps protect my paste wax and acts good as a drying aid. The price is right too. When I get it on a good sale I also buy Pinnacle spray wax. Looks great easy to use and I love Pinnacle products.
