I agree with Ron on replacing T&H with synthetic. If you do the job yourself you can save a lot of money. I have a C42 docked next to me and the owner replaced all the T&H with T&H and paid thousands of dollars on a 30 year old boat that hasn't yet left it's berth. We have synthetic T&H in our cockpit, on the deck and the seats and we love it. If I drop many more tools on the T&H in the cabin it will get replaced with synthetic.
