Does anyone have any opinions of waterless car wash solutions? Have you used them or do you know of anybody who has? I have a particular brand in mind "Detailer's Pro Series". It is offered through Autogeek.net. There are times during storage, trips to car shows and cruises that it would be nice to touch up the shine when there is no water around for a proper washing. However, I don't want to do any damage to the finish despite the claims made by the manufacture.
