FYI: I got around to trying this stuff out today,
DON'T BOTHER. Placed some on a piece of RadioShack
proto board and baked it @ 200 for 20 min to make
sure it was cured. Resistance test two holes, same
(top) side of board 0.40" distance = 5.7 Ohms. It will not
take solder, even after being baked it melts under the
soldering iron.
This stuff MIGHT be good for emergancy trace repair
( if you can glop enough on and not cause a short )
but call yourself LUCKY if it works.
This stuff and PTH? Forget I ever mentioned it, PLEASE
