Pontoon Cleaning Kit includes (2) Sharkhide Aluminum Cleaners - 1 Quart (1) Sharkhide Aluminum Protectant Sharkhide Aluminum cleaner is an amazing aluminum cleaner you have to try, you wont believe the result! Sharkhide Aluminum Cleaner is not like the other aluminum cleaners you will find at retail outlets. Sharkhide Aluminum Cleaner is a highly concentrated blend of Acids, and cleaning agents that you dilute (with water) to suit the severity of your application. It can be applied anywhere from straight to diluted as much as 10:1 or more depending on the desired results. Sharkhide Aluminum Cleaner is best applied to dry aluminum with an adjustable tip sprayer. Set the adjustable nozzle to the finest mist possible. Mist a section from the bottom up, let the foam work for a few minutes and rinse off. Thats it! No scrubbing required. Sharkhide Aluminum Cleaner will not harm carpeted bunks, paint or decals. When you are done, that old dark streaked and stained finish will be gone and you are left with a clean, uniform, streak free off white finish. In most instances, a couple of good coats can last many years. It's not uncommon to see three to five years of protection. On applications like motorcycles, muscle cars, show cars and other things that don't see a lot of exposure to the elements, you may see as many as eight or more years. In severe duty applications such as fire/rescue equipment, over the road trucks, dumps, tanks and the like, you can still enjoy one to three (or more) years of protection.
