I sanded some teak I salvaged from a boat yard 5 years ago. The teak came out of boats literally rotting away in a field. It came out great. I used a DA sander on the flat parts and hand sanded the radius areas then hit it with teak oil (several times until it didn't want to absorb any more). 60, 120 and then 220 grit. I'll post up some pictures on my thread here in the near future.
