I assume the graphite stuff is dark/black. Never used Fluid film, but sounds like its near clear. Graphite is good as lube where you don’t see it and don’t want buildup. Won’t attract dirt like grease. Definitely good for cables and roller chain.
The fluid film is a bit tan, but clear tan. Just makes the surface look kind of wet. Great on a used mower deck and blades, the slip pate great for new or rusted parts like exhaust manifolds, make them almost look like new.
