I have about 500' of 4-year-old cedar fence, with 4x4 posts sunk in
concrete foundation posts. Some of the fence has been beaten a little
with trimmers, etc, and it appears quite weak and brittle. Do I need
to seal it? Pressure wash it first? Or just leave it? For now its ok,
but I want it to last me 20-30 years. Are people treating fences like
decks here on this group?
