I saw a commercial of Turtle Wax Liquid Ice.
Just spray it on and wipe it and it is a wet look shine.
My Merc dealer uses Protect-All on all the cars so I use that on my car.
You can buy it at walmart in the RV section. (I have not seen it in the car wax section?)

I can tell you first hand the shine stays and the surface stays like slick glass.
I guess it is all basically the same stuff...just depends on how much time and effort you want to spent making your car shine.
It works for me!
