Hi Marshall,
Argotect is supplied in australia by Johnson Mathey. I use it
for all my soldering. Even though the tech info says you can’t
use hard and medium solder with it! It does “fume off” when
heated so you should have reasonable ventilation. The label says
it contains fluoroborates. reagrding firescale, I find it works
better than nothing. ie not perfect, but helpful! It is a fairly
thick white cream paste. best wishes
