Well Armstrod, did you follow your own advice? Did your cables install themselves automatically?
If not, it was not genuine automatic transmission fluid.
As for exactly the same as WD 40 or automatic transmission fluid, why do you think that, or are you joking like I am in my line (above) ?
Caig Pro Gold from their web site is $10.95 for the small bottle, enough for 150 (+) connections. I know personally, several high end audio manufacturers that use Caig on AC connections, tube pins and RCA / XLR connectors. While not as good as the Walker Silver, the cost is insignificant by comparison.
