I bought a new mailbox and cedar post from Lowe's. I was thinking of staining the post before installing it. I love the look of stained wood. Would that help it last longer outside? As well as the part that gets buried?
Staining the cedar mail box will definitely prolong it's life . Use an exterior stain, like one that is made for a fencing and decking. Most places can tint the stain to your desired color, or have them in pre-made colors. Hope this helps. Let me know if you have any more questions.-Gregg Home Depot
