I know this isn`t grease,but I figured this would be a good place to post about it. I`m wanting to get the best type of lube to keep the ignition in my car smooth and lubed up. Would something like RP Maxfilm be a good choice? I also was thinking about spraying it in my home stereo receiver`s attenuator and bass/mid/treble knobs. It`s from the mid 70s and the knobs make a bit of a crackling noise.
