I put it on the surfaces of things like table & band saw, use it for a decent penetrant with lubricating properties for locks, faucets, miscellaneous automotive stuff, etc. I've had a can of that stuff on hand for probably thirty+ years. There is about no end of things I'll spray it on.

I don't currently have either, but that's exactly the kind of surface/protection that I'm looking for.
