Yeah a chain will cut it up.... but the chain will damage almost any coating. It would probably hold up pretty good when a strap loop is attached to it.

Either case I'd just give them a re-dip after they get tore up... just like how I'd respray them with paint if I went that route.

I've had pretty good luck resealing the containers after use. A few layers of saran wrap and a few turns of duct tape seals it up pretty good. I've redipped tools after a year using the same can.
