Since nobody has responded to the question about CRC 6-56, I will....In my youth, I worked in a boatyard on Md's eastern shore. Many times i used CRC 6-56 to spray the insides of wet distributor caps and rotors, spark plug wires, etc. CRC 6-56 came through every time, turning a non starting engine into a starting engine. Its good stuff.
