Another thought on wood. It's one of those things sooner or later that when water gets in it starts to decay. Unless you hermetically seal the wood, it's almost impossible to achieve, it will happen. I don't care if you use Valspar, varathane, epoxy, cracks will happen. Even the newer version of low VOC Thompsons water sealer is close to a waste of time. If you still have the old stuff it will last longer.
