yeah I used a roll on rubberized sealant, they use it as a slip coat for flooring before they put tile down, on the floor it comes in a few colors but I used clear, also the grey color on the walls is Kills paint which is a great base it seals the wood but not from water. That would be the best bet I think or you could cover the whole thing in Silicon but thats a lot of silicon and would take forever. Thanks for all the kind words guy/girls!
