I was skeptical but I was looking for something I can handle doing by myself, I have severe arthritis and can be difficult getting around. And I must say, I'm impressed! When I was finished, it looked like I just waxed my car! I bought the trial kit to see if this will be something that actually works and something I can do myself. Only thing I wasn't happy with,is the pump spray bottle, it sucked, and I watched the video several times.
