  • Sharkhide Aluminum Protectant Quart
Sharkhide Aluminum Protectant Quart is rated 3.1 out of 5 by 9.
Rated 4 out of 5 by from Pretty good I have used Sharkhide on my boat aluminum for several years. After polishing the surface I apply 2 coats letting dry in between coats. It does dull the surface a little. Kind of a satin coat. It would be better if it didn't do that. I usually re polish and re apply every year as the aluminum will slowly oxidize. It oxidizes after 1 to 2 uses without it. It is not the perfect product but is 100% better than leaving the surface bare. I don't know of anything that works better except possibly powder coating with clear. Then the part would have to be billet and not cast as cast will have air bubbles come out. Polished aluminum is tough to keep shiny.

Rated 5 out of 5 by from sharkhide This product is great!!!!! I have used it in the marine field for years.I use it on pontoon and aluminum boats to keep water and scum from staining and adhering to their surface. Its an easy product to use and lasts a long time. This is the only product I have found over the years that you can apply to aluminum that will honestly protect it from the elements.

Rated 1 out of 5 by from CHANGED MY PRODUCTS LOOKS Put this stuff on my polished billet wheels and engine parts-BIG MISTAKE. This stuff looks like a yellowed coat when applied and does not flow out smoothly. I threw the remainder away.

I have Sharks on my pontoons. It was beautiful until buoys rubbed one of the sides. How can I touch it up and remove the black parts. I love my boat to look beautiful. I spent a lot of money having it done.

About Sharkhide Aluminum Protectant Quart

SHARKHIDE is an ideal long term protectant for aluminum, copper, brass, steel and fiberglass. It protects against stains, oxidation (rust), weathering, salt spray and pitting. The materials that make up SHARKHIDE Metal Protectant are a proprietary blend of many types of resins.These resins are then suspended in a blend of two different solvents. When applied to a surface, the solvents rapidly evaporate leaving the actual SHARKHIDE Metal Protectant behind. This forms an air tight film over any metal surface, and will protect against just about anything Mother Nature can throw at it.
