Actually, that's exactly where I started... a very thin coat on the bottom half of each pin, as it will spread down the pin as it is inserted. A similar but lesser effect as a.c. conditioning... and I felt that way with a BPT already in the system for about a year IIRC. Dislikes? None! It dries within a few days to a powder coat, no mucking or clogging in the holes what-so-ever. After 9 or 10 months I wiped off the pins on a tube (and rca pins etc.) and the surfaces looked brand new, same again after a year and a half! No visible oxides at all...
After treating the tube pins I painted all my signal wiring contacts and later, much later, went back and did all the a.c. contacts as well, including fuses.
