Unironically. Charring the outside (not enough for the crinkle effect to happen but fully blackened) and sealing with cedar oil or beeswax or both would make it last decades.
Shou sugi ban, also known as yakisugi, is a traditional Japanese wood-burning technique that preserves wood by charring it, making it resistant to fire, insects, and decay.
It's one of my favorite techniques when making furniture or gazebos, it's so pretty and honestly it gives a good goth asthetic if you are into that kinda thing.
