Best material for ride pad on 1/8 hydro?

[tunnelvission]

I'm refurbishing an older hydro and was wondering what would be the best material to put on the under side of the sponsons and stern ride pad? I read somewhere that carbon fiber with a light wet sanding on it to break surface tension was the way to go...... But I was wanting to see what everyone's opinion/suggestion was.
The boat I'm working on is fiberglass with wood frame work
Thanks ahead of time for any input
