Sorry no advice an carpet padding. Just a little Kingscraft info. Pluckebaum actually sold the plans and info to Kingscraft to start building boats. They built a few hulls for them also. Pluckebaum also built for Marrinette. So the Kings and the Plucke are like first cousins. This info came directly from Dennis Pluckebaum.

Kinda explains the similarity in the design of the boats.
