My two cents (Though they be a little late)
You definitely should get something on the existing.
If it's soaking up water drops then it is basically unprotected.
What that should be is probably open to suggestion. My first thought is probably wax if you can stand the maintenance.
(Assuming you do not want to sand and finish them.)
Matching something new to something that old is gonna take some doing/experimentation.
(Same assumption as above)
Probably do-able though.
Where are ya?
