Anyone have any experience or thoughts on it? It seems like a good device that " removes" the minerals and particles from water. If you don't need to towel try it would reduce some micro marring or scratches.
i use a blower,works fine for me no marring, but will have some water dropplets to dry with a towel just blot them.
I would never leave water on the car like that.... it does significantly help. especially when the sun is out if you don't have a shady place to wash and dry and in the jambs and things of that nature.
