[A/S] What wax do they use at the automatic car wash?

[Jerry Flanders <jflanders2@xxxxxxxx>]

Anybody know what is the material they add in to the final cycle of the 
automatic car wash (the "touchless" one, where you drive in and the wand 
comes over the car with a multi-cycle wash). I sure would like to buy some.

When we were in Anchorage this summer I used a coin operated RV wash to 
clean off some of that Alaska mud and was pleased with how effective and 
easy it was to clean up my trailer. I only used the wash and rinse mixes in 
the high-pressure wand that time, but they  had another cycle with a 
finishing shine coat of some kind.

After coming home, I got out my high-pressure washer (which I had used 
before only to clean up the bare patio concrete and strip some paint on my 
deck before re-painting) and had a go at the trailer as well as the truck. 
Worked VERY well, and was easy to do (you just hold the wand about 12-18 
inches away and let it blast the surface clean).

I think this would be an easy way to apply a wax to it also after the wash, 
just like the touchless car washes do as the last cycle, if I can find out 
what they use and where to buy it. Some of the pressure washers have an 
auxiliary suction hose that you just drop into the bucket of whatever 
solution you want to spray.
