Some guy at the gas station had a table set up trying to sell this stuff to everyone pumping their gas. He was going around with some dirty old rag and a can of the waterless wash (which is in an aerosol can lol) and demonstrating how the product worked on everyone's vehicles. Paint, glass, wheels, you name it, all with the same rag.
Then as I was pumping he came up to me, I tried to turn the other way but he started talking to me. I told him no thanks (trying to be polite). Then he insisted on me to let him demonstrate the product. He pulls the dirty rag out of his pocket and said "here let me show you".
At this point I was freaking out. I literally yelled "NO STOP!" right before he was able to wipe down my paint, which was dirty because it rained the day before.
I probably came off as rude but if that's what it takes for him not to touch my car and swirl the hell out of it then I'm fine with that.
Now I continue to see tables set up at random gas stations and the people are trying to sell this stuff. I looked up the price and it is ridiculously expensive. You could get UWW+ concentrate that makes 5 gallons of product for the price of one small aerosol can of that stuff.
