The foam backing on my vinyl has basically turned to dust. I've removed it the best I can. For simplicity, I'm going to replace it with foam backed vinyl again, but I was thinking I'd used closed cell foam so that if (when) there is a leak, it won't act like a sponge. But, I can't find vinyl with closed cell foam backing...it's all latex based open cell. I read another thread where somebody glued closed cell onto vinyl and then glued that to the hull
Is there a company that sells the closed cell already attached to the vinyl? If not, is there a reason that would be a bad idea?
