Maybe he meant best touchless...

 

The only "waterless" I could think of is this:

http://www.dri-waterless-car-wash.com/

I've personally tried this product (on my Tacoma). It does a decent job. But to be honest, it will scratch and/or leave swirl marks no matter how much you apply this product on a dirty surface.

Nothing beats the good ole' rinse, dry, and wax routine, IMHO.

 

Hrm, the only time I've seen "waterless" car-wash products used was on trailer queens at classic car shows. Never on a car that's actually driven.

 

think this is what your talking about i got it for free from a friend.........but i will never use on my evo
