dritter,
While the Boat Clean and Boat Scrub are stand alone products on their own, I use them as part of my annual treatment of my non-skid surfaces, ie, bow and swim platform. I clean the surfaces with the Boat Clean then I use Boat Scrub. Once dry I follow with two coats of the Sure Step, 24 hours apart. BTW, that's Aurora's recommendation. I never use the Kwik Shine on the non-skid, but it does a great job on the interior fiberglass as well as getting rid of the dark streaks that seem to show up whenever it rains.
