There is special electrical contact grease, loaded with graphite, that would 
probably be the best choice, but anything would be better than nothing.

The key is to fix the worn contact spring before things grab and destroy 
much larger parts. The contact ring on the underside of the wheel is also 
replaceable and might even be available from the dealers, as I suspect it 
was also used on Beetles (and I think I've seen references to it on BMWs, so 
it may have been a common German approach in that era.)

Up to '70 VW did things completely differently. The ground path was 
complex and confusing, but it didn't have this problem. It had its own 
problems, but they didn't lead to destruction and they could all be fixed.
