Hi, I have a friend who recently discovered major rot in the wood stringers of his 1978 Trawler. We have been discussing alternate materials for replacement and wondered if we could make new stringers out of ferro-cement. We would basically make a mold, lay up the stringers and then fiberglass over them. Does anyone have any experience in this or have any suggested methods, mix recipies or resources?
