The total contact paste is really not a paste as the consistency helps it spread very easily and a little bit goes a long, long way. The kit comes with a nice painters style mini brush that is used to paint all connectors Etc...
I simply paint the surface of the solder connections and component lead outs on point to point wired crossovers and tube amps. I also paint the tops of capacitors and transformers.
One just needs to be very careful not to produce an unintended conductive bridge. Just use a very little amount on the brush as it spreads very thin, and as I said l, goes a long way. Do not apply so it’s thick and gloppy, but rather thin and spread evenly.
It also works wonders on power cord spades, speaker connectors, RCA male pins, tube pins etc...
While inside my speaker crossover I also pasted/painted the internal speaker wire connections where they solder to the drivers.
Many won’t go as far as I did as they are not comfortable working inside of gear and I understand that. However, a good place to start is certainly on all the various connectors in our system.
