Can anyone recommend a Warterless Car Wash that wont scratch you car's finish? I have a show car (70 SS Chevellel) and with being pollen season here in the Northeast, I finding myself carefully wiping the car down with detailing spray everytime I go to a car show... After a couple of hours, the build up on the car is great that I dont think detailing spray should be used. Im trying to avoid swirls .. any recommendations??? Thanks in advanceFeed back please
