OK, my first post here.  My Old Town polypropelene canoe needs new transom wood pads.  One goes inside, the other goes outside the square back end so one can mount a small motor to the canoe.  Anyways I have made new wooden pieces out of white oak.  Any suggestions on how to finsih them?  Also my fishing boat needs new wooden seats.  I picked up some marine plywood to make new seats with.  I  would like them to last a while.  Can you recommend a finishing product or method.  These will be used in freshwater only.  Thanks   JK
