It may have the surface tension advantage, but the numbers I saw show flourinert to have a very low specific heat. (.23 or thereabouts). Straight ethylene glycol is ~.6 and 30/70 glycol/water is ~.9, so that is pretty significant.
In that case, running straight anti-freeze might be a better (and much cheaper) option. I don't know if that helps the Al-Ag situation however.
