My neighbor and I are putting up a fence between our properties. We will use either Cedar or Redwood. The fence will have vertical boards on both sides bc we want both of the fence surfaces to look nice from our respective properties.
My question is should we finish/treat the fence AFTER it is installed or treat the wood before it is installed?
Also after it ages how do I treat the wood? Note: There will be faces that are 'hidden'... the back sides of the faces that we see from our properties.
