This stuff is magical, and is really what makes the color of your faded boat come back. You do need to completely deoxidize your boat before applying this stuff. I find it is best to spend a few days on the process. I use a dual action buffer with a heavy cutting pad (or 2) and #67 to get the oxidation out. Then after a day to let the gelcoat rest, apply this stuff with the DA and a medium polishing pad. Repeat two more times, allowing the gelcoat to rest a day in between! If you rush the process, the color will fade faster. Immediately apply a coat of Ultimate marine wax after your third, spaced out coat of polish. A second coat of wax the next day will pretty much make your docked and lifted boat stay gorgeous for a year. If you don't have a roof on the dock, you should rewax halfway through the summer.
