Very interesting story about your lock problem and I hope all is well now with it. But guys, I thought WD40 was " The Product " for all cures and I have used it for years in a rusty old padlock on the garden shed that stores bitz'n piecez I hope to one day throw together into a '28 A Roadster, so I don't go into very often so a squirt of WD40 up into the padlock does wonders as I have never had trouble getting into the shed when needed. Now that non talking man tell us never use the product on locks, go figure...
