I agree that one should not use excessive amounts of any enhancer. Nor should one repeat the treatment over and over again. I have read warnings about using Walker SST on tube pins, because of the heat issue raised by Elizabeth. But is there real evidence that ProGold bakes on and forms a non-conductive goop? First of all, it seems to be a fairly dilute liquid. Just the act of installing the tube after a single treatment, even assuming one does not wipe off the excess liquid a priori, would tend to re-distribute the suspension (or the solution) such that there is mostly metal to metal contact between pin and socket.
