Most of the products with silver as the conducting agent would be suitable, Silver Print etc. Silver is good conductor, compatible with copper, iron, tin, cadmium combinations and is able to operate at the temperatures found around automotive electronics. Its oxide and sulphide products, the blackis= h tarnish that forms on the surface under adverse conditions over time are also conductive. Aluminum is not good stuff in the presence of moisture and electric currents as tends to form non conducting oxides, become anodised.
