My dad and I painted our duck boat with
Tuff Coat Paint on the inside of the hull. On the outside we used the Tuff Coat Paint primer and then painted it with a
Camo Stencil Kit. It's used in brackish water, sandy, rocky environments and so far has held up well since we painted the boat two years ago. I really like the Tuff Coat brand products. The boat was an old Starcraft aluminum boat we got for free from a friend who had it hanging in his garage for 20+ years. The Tuff Coat inside is a great non slip surface and does seem to deaden the noise a bit. I think the primer was the key and making sure the boat was super clean before application of the primer and paint.
