On my recent camping trip, I put a dent in my small backpacking pot that I use for cooking/boiling water/etc. It looks like the kind of dent that you could just pop out, but because of the angle and the strength of the metal I haven't been able to. I tried filling the pot with water and freezing it to see of the ice would expand and push it out, no luck. The company that made it says the pot it made of Halulite (basically hard anodized alluminum). Any suggestions for how to get the dent out?
