So I bought this Planet Waves humidity controlling bag, which has some sort of water retaining material inside. I did this because I don't get the Martin out very often, and I wanted to preserve the wood. Well, over time, unbeknownst to me, the material in the bag broke down and leaked some kind of oily liquid in the bass and soaked the wood, destroyed the finish, etc. I'm going to send it to Martin, but I'm thinking the wood is history. I'm figuring the best they can do outside of rebuilding the box completely is treating the wood with something to stabilize it and make it take a finish again, but nothing can be done for the discoloration and whatever damage has been done to the wood fiber. It even damaged the original Martin strap I got with the bass over 20 years ago. This kills me. I bought this bass brand new, and it's worth a lot of money. I would say don't buy that product, but it's no longer available anyway.
