Bottom Line

A kit that comes with 3 products to clean, restore, and protect your boat's exterior.

Pros

Goes on easily with a sponge or a cotton buffer pad. Oxidation cleaner removes small amounts of oxidation very well. Polish delivers a nice gloss. Restores the overall look of your boat effectively.

Cons

While this product seems to work well, you will still have to put a lot of elbow grease into it or have a buffing wheel to get the most out of it.
