Are contact treatments worth the money?

Hmmmm...sounds like many of you like Walker Fairy Goop. I am going to rent an electron microscope and see what happens at the intersection of current, metal and goop.

hmmmm. any scientific testing to back up the implied improvements? Got to watch out for that placebo effect.

It is agreed that cleaning connections is a good idea and then perhaps using some type of silver conductive grease may offer sonic improvements YMMV.

That MG 8463-7G costs about $16.00 plus shipping from an industrial supply house. I wonder what that have at the auto supply store??
