Color Sanding is what is done to your boat right after it comes out of the mold. You use 1500 grit sand paper and a bucket of water. You soak the sand paper and I also use a spray bottle and spray the boat with some water and do a light sanding on the gel. I do this in areas where I have noticeable scratches. After you wipe it down you take a wet sponge and clean the surface again then use a detailer like Showtime from Mothers. The gel will look very dull when you are done. The next step is one that varies but I have a neighbor with a Shiada and he is very anal about cleaning it. He turned me on to using Mothers Wheel cleaner polish as the next step. It is not as course as a rubbing compound and a bit more course than a color restorer. Next step is color restorer, then polish, then buff. Gel on a boat much like paint on a car will look faded because of many little scratches all over the surface causing the light to reflect all over the place. Once you eliminate the little scratches you start to get the color and shine back. The color sanding helps with this process. Someone one here posted another product that many Corvette and fiberglass car guys use. I was thinking about using the system on my new boat when I get it. I will do a search and see what I come up with.
As for polish I like the driven line. It really brings the color out and the water will bead up and not stick to the boat. I get less water spots when I use it. I don't know the technical mumbo jumbo I just know that my boat look its best after using it. BTW I have 1992 boat.
