There is currently a thread where-in a small discussion about ensuring track electrical connections took place. This brought to mind a product mentioned on another thread that is supposed to help to maintain good electrical connections. The product is Silver Conductive Grease, Temp -70 to 485 CW7100. This stuff is pretty expensive and you don't get very much for what it costs.
Does anyone know if it is actually worthwhile (considering the cost), and how far does it go? How many pieces of track can be treated with one 6.5 gram injector tube?
