Oh wait, that's not the ad!
I don't want to get sued...
Ballistol, or as I call it; the German WD-40, is top-notch.
I've used it often since the mid 1990s. It's good for rubber, polymer, metal, wood, etc.
I wouldn't apply it to painted items or a few other materials(like suede) but the warnings are on the green can(in English,
).
Ballistol is also non-toxic & CFC free. Plus it has a light pine scent.
Go green!
