You're probably aware of it Mark, but just in case - I'd be leery of using
DeOxit around the insulator portion of the plugs. No idea if there's
anything to worry about but I do know it has a bad effect on older phenolic
wafer switches, causing them to swell and bind. It can usually be reversed
with alcohol (phenolic before self) but better not to end up there in the
first place. I learned this from a WWII-era SX-28A I worked on, it froze
the band switch completely. Still turns hard today.

As Ken indicated, 'sparingly' is the word of the day here.
