Existing surface rust is something I did not consider although I did flush my vehicles with Zerex Super Flush.

I've seen some pretty murky stuff in the company vehicles, but that was DexCool, not G-05. Any time you change coolant on a vehicle with unknown maintenance, I would recommend a citric acid flush (fill with 10% citric acid and run till fully hot, cool and then flush till it's clear) --this will dissolve all that rust and carbonate sludge that has collected. I also recommend using at least low mineral content, if not distilled, water with G-05 (pre bottle recommendation) -- hard water may cause tons of crap to precipitate.
