Does anybody use fluid film on their firearms? I've been using it for exterior wipe downs of my hunting arms for a while and its been great. Even protects the wood stocks as well as leaving a nice shine. You can leave a heavily wiped on coating for storage or buff it clean for field use. Seems to offer far superior corrosion protection than the majority of gun oils. Haven't transitioned into internal use, yet. I'm sure it would be fine but it likes to collect gunk in other applications plus I'm not sure how well it would hold up to any amount of heat.
