I was duck hunting with a friend in an aluminum boat. He had it sprayed with LineX bedliner to deaden the sounds plus less noise from the hull on plane. I tought it was a great idea for hunters and Fishermen both. I called Wayne from LineX of Puget Sound (lynnwood). He told me a 14 foot boat would run about 350.00 est.. Not bad. I may get rid of the old carpeting in my boat to replace with this stuff.. I thought it was a great Idea so wanted to pass it along. I wonder if it could be used on the bottom as well to protect from rock and stump damage??
