A reference to sticky knobs on another thread reminded me of this. After 3 decades of fighting with sticky knobs on field cameras, I finally found something that works like a charm, dry but slick. Pedros Ice Wax. 2 onces will last a lifetime, as I only have to put a drop on every lock knob about every two years. I have been using it now for going on 8 years.
