Between what I saw on the Mar-K website yesterday, and all y'alls responses, Mar-K is going to be the way I go. I do plan on painting the boards black. I have strips from my old '65 that I had to dismantle, so I can clean those up prior to tearing things down. Thank you for your insight and knowledge. It'll be nice to have straight boards again, but better yet, boards that won't warp.
