I used this in conjunction with the Carnauba wax first using their compound to remove the oxidation on my 5th wheel. After the cutting compound then the polish and wax it really looks good again. It was a lot of work but well worth it. I just hope it last a few years before I have to do it again, but for now I'm really happy with the results. Just make sure to follow the instructions with all three products and you will like what you see. I had a couple of questions and Meguiars tech support came through. Good price and shipping right to the door what more could you ask for except someone to do it for you..
