Love the Boat Scrub, won't leave the dock without it. Also, love the Sure Step, great way to keep non-skid clean and bright. I hear the Kwik Shine is good but haven't used it.
The Premium Boat Shine, however, didn't work out for me as I expected. After I apply it, the boat won't let go of it, no matter how much time I leave it on or how quickly I remove it. So actually after the Boat Scrub the boat was much shinnier than after I did the Boat Shine which made it a bit duller again and left some streaking. Even a buffer wouldn't do the job of taking it off! Actually it worked fairly well below the rub rail, but not above... I have no idea why. Tried it in different temperatures and in the shade.
