Here's the boat we used for our latest 3-day detailing class where the 3rd day is Extreme Boat Detailing.

Aluminum Diamond Plate Fenders
This type of fender is very common in the boat trailer world. When detailing boats for a business, it's a normal expectation that besides detailing the boat, you also detail the trailer, or at least the fenders. Many boat trailers like this one are made from steel, unpolished aluminum and/or galvenized steel. Galvanized steel trailers have a liquid zinc coating designed to help prevent and slow down rust and corrosion. When it comes to these three types of trailer materials and/or coatings, there is little you can do to improve how the trailer looks EXCEPT for removing the oxidation on the diamond plate trailer fenders by polishing to restore a brilliant, chrome-like appearance.
Here's the fender on the Starboard side of the boat.
Personal Opinion?
I don't think these aluminum diamond plate fenders have EVER been polished or maintained. The level of oxidation and corrosion is off the charts!
The level of oxidation and corrosion is severe.
Photo-documenting the before and after condition
I always do what I call, preserving the ugly, by covering the side of whatever it is I'm demonstrating on to - preserve the before or the ugly.
After results
Below are a few pictures showing the after result from removing the oxidation and corrosion.

15 to 20 minutes
This took me around 20 minutes from start to finish to remove 33 years of oxidation and neglect and provided the finishing touches to this boat detail.
