Sharkhide Aluminum Protectant Quart is rated 3.1111 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.

Rated 5 out of 5 by from Excellent product! Put this product on a set of JEGS Performance Sport Star Cast Aluminum Wheels about 4 years ago. The rims have been outside on the car for about a year now and were washed two weeks ago. Check out the pic.

Rated 2 out of 5 by from expensive and didn't work well on mc parts I decided to spend the extra money on this protectant with the hope that it would be a good cover for some aluminum motorcycle cases I am restoring. Here were the problems, when following the directions there is some sort of rainbow type streaking that occurs which really takes away from the polish of the aluminum. The other thing is with uneven surfaces when applying it is hard to see what is being covered. With their recommended application method of a cloth it is hard to get to uneven surfaces and see if you did cover them. A spray type method would work so much better. Lastly I had to transport these pieces after covering with Sharkhide and covered them with a saran/plastic wrap. The wrap on the Sharkhide covering left marks which makes me wonder how this stuff would hold in the long. What this all means is I get to strip it all off again and either leave bare aluminum or find another protectant. In the pictures you can see the rainbow type streaking that occurred along with the damage from simple saran wrap touching the dried for many days surface. A lot of money for a lot of disappointment for this buyer. I would have given it 1 star overall but maybe if you have an aluminum surface where appearance isn't important this product might work. Thinking about returning it back to Eastwood for a refund.

Rated 4 out of 5 by from Another excellent product I trust Eastwood to only offer products that work as advertised. Are they cheap? Yeah, NO. Sharkhide is no exception. Only time will tell if the claims are true regarding the reapplication interval, but I don't think Eastwood would risk their reputation.

Rated 1 out of 5 by from Did not work! I applied this product as directed by the manufacturer and after just one year my aluminum stairs started to oxidize. It was a waste of money and now I need to start over again.

Rated 3 out of 5 by from Just Purchased I am primarily using to coat original bolts and clips on a 1957 Thunderbird, It is difficult to get cad plating and I am hoping this will keep this hardware from rusting. We will see. The product is rather pricey when you include shipping but if it does what it states it will be worth it.

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.
