Dayton Poly's are what I used as well. If I recall I had to drill small holes in the pot housing to get the deoxit straw in there. I think I used a label of some sort to cover it up when it dried. I could swear later on that someone told me the housing can actually be removed from the pot - oh well. Maybe you lucked out and yours were cleaned as well. How do you like your Mach 2's? I have a pair in my basement that need a complete restoration.
