I have an old wood fence in my backyard. It's at least 10 years old
and is in marginal shape. The wood has never been stained for sealed
as far as I can tell and is badly bleached and sun damaged.
I do not want to replace this fence and would like to do some minimal
repairs to extend its life and improve its appearance. What is the
best way to clean and treat an old, sun damaged fence?
I'm going to replace the boards which are rotten.
