Never tried that on really but I would say stick with the hard way if you want the best results..I have heard that stuff doesnt usually work to well but I could be wrong..
Yes I've used it and I'm hooked. You basically wet the car down, after that you just work in sections by squirting a small amount of gel on the surface and using a wash mit you create lather. I was using Mr. Clean and was not satisfied but with this gel I'm totally satisfied.
