Can you caulk over cracked caulk?

Answer:
Not the greatest idea, when packing in the oakum and then pouring the lead and caulking it the hub could split wide open

Your new caulking job will last longer if you remove the old caulk and any of its debris and make sure the area is dry before adding new caulk. You can use an old screwdriver to remove the old.
