Stabilant 22A - 15ml vial, with cotton swabs.
15ml is a tremendous amount of Stabilant, and likely enough to handle all the major connections in your car, with plenty to spare. We recently used 22A on our 348 and swabbed most of the major electrical connections in the engine (ignition components, throttle controls, crank position sensors, etc) and still had enough to do interior items including the door wiring connections and HVAC control unit.
We recommend using a contact cleaner FIRST to really clean the connections, then apply the Stabilant 22A Contact Enhancer. Amazing stuff.
