Leo, yes, we are planning on sealing it as soon as we have time!

BluegillerKiller -- i went back and forth on this -- i'm still watching them for leaks, so far so good -- but i may still rotate them so the seals are horizontal, which will keep them both out of the water except when there are several people on it. Thanks for the tip! Definitely still pondering this and keeping an eye on it. May rotate soon!

Thanks everyone, enjoying the dock almost every day!
