Today was my first time to try this product and based on a one time use, it was very impressive. The car it was used on had been parked in the garage for sometime and was dusty water spot dirty, not really too bad. It was a toss-up between the EZ Wash and Final Inspection. The EZ Wash did a great job and could very easily serve as a quick detailer. (IMHO) I used a spray bottle and needed very little, maybe 4 oz. total. The car was an '81 Vette, so there wasn't a lot of area. Windows, paint, and Rally wheels were done. I guess what I am saying is that it seems to be a worth-while addition to my detailing supplies.
