FLUID-FILM (and similar products): Eric's description states corrosion resistance, probably in the form of a surface barrier coating. He also implies it can be used as a penetrating fluid for freeing seized bolts and parts. It may also be suitable for use as an anti-seize compound, for bolts and parts that will need to be removed in the future. Finally, his description of its behavior over time implies it contains silicone.
Special note on compounds containing silicone: Silicone is useful in specific situations. In inappropriate situations, it is extremely problematic. Silicone is very tenacious. Once applied, it's effectively impossible to remove it completely. Silicone contamination is a well-known, massive issue when it comes to painting, powder coating, or varnishing things. Microscopic silicone residue creates very noticeable "fish eye" defects. In most cases, it's easier and cheaper to discard the contaminated item and use an un-contaminated replacement. (People are very aware of the consequences of bringing anything containing silicone within 30 feet of my woodworking tools. The same goes, to a lesser extent, for most of my other tools and work areas.)
OXYBLOCK: Appears to be a corrosion inhibitor barrier coating. It's probably what you see on reman brake calipers and similar parts. I have something similar that I use when appropriate.
