Review: One can goes a long way - Impressive product, easy to apply. Useful in many places for me. Review: Follow the instruction, go to Wal-Mart and buy some cloth diaoers and apply as instruced - I recently spent about 60 hrs cleaning and polishing my toons on my pontoon boat. I read and ordered this from desertcart but completed my polishing before it arrived. I did not want to put my boat in the water without some kind of protectant on it due to all the work I had done. I went to numerous stores before I found a product that was to protect aluminum. I applied it and went to the lake. Upon pulling my pontoon boat out that night I proceeded to attempt to wipe the water spots off and got really upset. The water spots were like minerals and would not wipe off, needless to say, I was quite discouraged. The next day I sprayed pure vinegar on it and wiped it down and it cleaned up very well and resorted to the fact that I was not going to spend the time to do this every time I went to the lake. I am a guide and am there every other day. I figured it would slowly go back to the way it was and I was o.k. with that. Then the next day Shark Hide arrived, I had already decided that I would return it and let the boat slowly go back to how it was. Upon opening the package I discovered it had gotten a leak from shipping and could not return it, I was a little pissed the way my project was going. I then thought about it, this is made by American Toon. It is for bare aluminum, not your car and your fiberglass boat and as an afterthought also aluminum. It is only for bare metal including aluminum. So I applied it as instructed and went to the lake that night. Upon pulling the boat out and clients leaving I proceeded to attempt to wipe it off as I had before on the other product and was prepared to be disappointed. As I started wiping it down, my exact words were Holy Sh.., this stuff actually works! It took me about 6-7 minutes to wipe my entire boat down and remove all the water spots. This stuff actually works. I have never wrote a testimonial before but as good as this stuff is I thought I owed it to them. Oh and by the way, they replaced my can that was 1/2 leaked out with a new one. Great customer service and a product that actually works. ## Features - Sold in 1qt Container - Protects boat from streaks, stains, water lines and oxidation - Protects in fresh, brackish, and saltwater - Easy to Apply - Won't chip, peel, flake, or yellow ## Technical Specifications | Specification | Value | |---------------|-------| | Item Package Dimensions L x W x H | 8.6 x 5.4 x 5.2 inches | | Package Weight | 1.95 Kilograms | | Item Weight | 2.2 Pounds | | Brand Name | Sharkhide | | Number of Items | 2 | | Manufacturer | Flatwater | | Size | 32 oz (1 Quart) | ## Images ![Metal Protectant | Polymer Protectant for Aluminum, Cast Iron, Copper, Brass, Bronze, Steel | Rust, Stain, Oxidation, Streak, & Weathering Protection - Image 1](https://m.media-amazon.com/images/I/81LGT3ogT3L.jpg) ![Metal Protectant | Polymer Protectant for Aluminum, Cast Iron, Copper, Brass, Bronze, Steel | Rust, Stain, Oxidation, Streak, & Weathering Protection - Image 2](https://m.media-amazon.com/images/I/91yjgXZEZLL.jpg) ![Metal Protectant | Polymer Protectant for Aluminum, Cast Iron, Copper, Brass, Bronze, Steel | Rust, Stain, Oxidation, Streak, & Weathering Protection - Image 3](https://m.media-amazon.com/images/I/61MHj8hrGuL.jpg) ![Metal Protectant | Polymer Protectant for Aluminum, Cast Iron, Copper, Brass, Bronze, Steel | Rust, Stain, Oxidation, Streak, & Weathering Protection - Image 4](https://m.media-amazon.com/images/I/51sEKujceXL.jpg) ![Metal Protectant | Polymer Protectant for Aluminum, Cast Iron, Copper, Brass, Bronze, Steel | Rust, Stain, Oxidation, Streak, & Weathering Protection - Image 5](https://m.media-amazon.com/images/I/51UZ4xCTtVL.jpg) ## Available Options This product comes in different **Size, Number Of Items** options. ## Questions & Answers **Q: Would this work on an unpolished Anodized Aluminum camper skin?** A: Yes, It was applied to the unpainted parts of my 16' aluminum trailer almost 3 years ago and it still looks new. **Q: How long do you need to wait for the cleaner to dry before you can put the Metal protectant on?** A: I’ve never used the cleaner. I just wash boat, let dry and go at it. It really does go on smoother and easier in the cool weather vs doing it when it is hot out and dries more quickly. **Q: Will this work on a set of new chrome wheels?** A: Yes, but they may not be super Shiny **Q: Can i use this stuff on my motorcycle, like the chrome and paint or will it damage the paint finish ?** A: not for paint chrome ok but test first ## Customer Reviews ### ⭐⭐⭐⭐⭐ One can goes a long way *by R***H on March 16, 2026* Impressive product, easy to apply.

Applied to the toons on my tritoon and they still look new after our first year in saltwater. Take your time on applying the product and make sure you get full coverage. I can see every small place I missed.
