Good tip.

PAM works to on snow shovels and also on aluminum tent poles and other things in extreme cold which might use a bit of lubrication. Wax will also work. But if temperatures are highly variable both wax and PAM can melt, smear and stain. Worse if you got carried away and used too much.

An alternative that works to keep things sliding in all temperatures is silicone. The spray is easiest to find but liquid that comes in a bottle with a cotton swab inside lasts longer and is cheaper in the long run.

Silicone works almost as well as PAM in extreme cold but doesn't melt or run in heat and won't attract dust or grit. Applied to cloth it is a fair water repellent. If you really soak it the cloth will slow or prevent corrosion of metals you wrap in it.
