On my car I found it better to attach a brush made out of spring steel
above the uppermost rubber coupling. My horn was intermittent; I had
retrofitted a horn relay and I think the problem was high resistance not
letting enough trace current to activate the relay.
It worked when I had a spot-inspection by the DMV, so I'm happy :-)
Spring steel of the type I used is available in the form of strapping.
The post office should have piles of it, as should hardware stores and
anybody else that receives bundles of "stuff" wrapped up with steel strap.
