I was amazed by the Sharkhide. I went down to the lake over Thanksgiving weekend and checked out the boat. The Sharkhide really did what it was supposed to. The logs were shint like I just polished them but the areas I didn't do, the very bottom and the insides were all tarnished, amazingly so for just 3 months. Definitely get the SHARKHIDE. It's worth the cost times two!
