I had a look in my tool pouch today and noticed most all the tools were pretty rust. The pouch seems like a decent quality, almost like it is insulated. But I suspect condensation is the culprit. I decided not to put the tools back in the bag, rather I just taped them up together with electrical tape. And sprayed them with Rust Check. And added a piece of rubber as a dust cover. Hopefully I’ll never have to use them.
