Have an 85 Bayliner Capri. The storage underneath the deck, that you can lift up, the edge that is right next to the drivers seat has rotted. I cut out the rotted part, and am about ready to install the new wood. Although, I need to water seal it. I have treated greenwood already. I have Thompson's water seal, on my second coat today. Any other suggestions on how to keep it from rotting, or how many coats or anything would help out a lot!! Thanks in advance!
