I bought this product to restore the finish of our Seadoo's, 1995, 1996 Xp's and I was impressed. This cut through the oxidization quickly, finishes down nicely, and leaves a great finish. I also bought a polish as usually you need to use a polish after a heavy compound (or so I thought) but not with the M67. I was able to skip the second polishing step all together. Sealed it with a nice wax also by Mequiars.
I used the Porter Cable 7424 XP, CCS Orange cutting pads 4 inch on a 3.5" backing plate.
