the thing we have found on some of the detailing sites is it works well, but there are others that are far more economical nad work just as well. This is a 32 Oz for 12 bucks - that's 8 car washes per bottle,
Duragloss with carnuba rinsless is 12 oz for 10 bucks and is 1 oz per application (2 gal) in 12 oz bottles - that 12 washes per bottle - 4 more washes free.
The same with Blackfire and Optimum no rinse..more washes per bottle.
And yes, I have used all of them incl the turtle wax...and I do like it.
