I went out and bought this product today http://www.griotsgarage.com/product/spray-on+car+wash+kit.do?sortby=ourPicks
WOW just Wow!! This product is amazing. First off, I do not sell nor know much about this company. It was recommended to me so I thought I would give it a shot.
It is cold up here in PA. Car was dirty...well not anymore. No water what so ever!
I am a bit awestruck by this stuff. Enjoy!
