Our boat was in storage for 2 years because my work schedule was not allowing us any free time. After getting it in the water and starting the interior cleaning process this year, we noticed the dash had several small cracks and looked like it was very dry. We used a different cleaner that we had on the boat and it just didn’t seem to be helping it much. I grabbed the Serious Shine and read the label. Thought that it couldn’t hurt to try it. It worked Awesome!! Took me 2 coats as the fiberglass seemed to suck it in but man did it turn out great! I’m new to Shurhold products but the more I use their products, the more I become a loyal customer. You really don’t need any other products on your boat. Shurhold has it all!
