Sharkhide Aluminum Protectant Quart
Product Review (submitted on October 27, 2009):
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.
