Nancy wrote a question about Bear Vault BV500 Bear Resistant Food Canister on July 30, 2011
When we use the vaults in the rain, we find the lid very difficult to unscrew. It's as if the humidity creates a friction and resistance in the threads that makes it extremely difficult to turn the lid. This is before we push the tabs to open --- we're just trying to move the tabs into position to depress and open.
Any ideas? Might using some paraffin on the threads help counter the effect of humidity friction?
