What is the best finish to use on a kwila outdoor table. It sits next to a salt water pool so needs protection from splashing. I have been using furniture oil as it was only purchased it 6months ago. Is it OK to use deck oil in place of the furniture oil or is there something better altogether.

PS It is 2.3m long hence thinking maybe decking oil as I buy that in 4L tins for the deck already and always have a bit left over in the tin.
