Seems like 10 or more years ago, the little packets of goo that came with brake pads was very silvery and appeared to be anti-seize. It was even mentioned in repair manuals.
I think VERY thin layers on metal to metal sliding components will probably work. Maybe not the best lubricant, but it will keep parts from bonding together. BUT, beware that it is a petroleum based product and could ruin rubber brake components if it touches them.
In fact, I think that is why it has fallen out of favor as a brake product. Lawyers and garage gorillas that slathered it all over brake components probably resulted in court room three ring circus.
I have two products from GRW (or GWR) auto: pastelube and ceramlube. The pastelube is a moly paste designed for the "outside", exposed components. Put some on your palm and try to wash it off with water. Impossible. It is the most water resistant lube I have EVER seen - miraculous.
