I have used the Loctite copper silicone since recommended by Steve and have never had any problems. Secret is to apply a very small amount, just enough to provide a thin smear. It doesn't set hard and is easy to remove by rubbing off with a cloth or your finger. I have bought two tubes over the years, simply so that I can have one in the garage and the other in the car.
