If you sweat on the gun or the gun gets wet in any way during carry/use it needs to be properly cleaned, lubed and otherwise maintained. No super lube from anyone will protect against lack of maintenance.
I live in the heart of the rust belt it's cold and wet in winter and hot and humid in summer. My guns don't rust, my cars don't rust, my tools and equipment don't rust or corrode and it has everything to do with proper stringent care and maintenance.
For civilians perhaps this is an option, but for most folks with serious duty weapons, including concealed carry, it isn't feasible to clean and maintain in a holistic way every day.
In no way am I saying you're lying, but excerpt below strikes me as implausible.

Please tell me of your secrets related to cars. I grew up between I70 and I80 with lots of salt on roads, blizzards, and occasional lake effect snow, and even with winter carwashes, by 20 years the floorpans had rusted through on most vehicles (and maintenance due to rusted bolts, etc., was a complete PITA).
Now in Texas, I regularly work on and drive 30+ y/o vehicles that have never seen the coast and only rarely seen salt on the roads... Keeping rust at bay is simply a matter of seeing it -- and then addressing it w/in a 10-15 year timespan before it becomes deeper than cosmetic... Biggest issue we have here is peeling clearcoat and fragile, aging plastics exacerbated by high temps.
But a 30 year old vehicle in that Great Lakes state would have holes in floorboards regardless and the frame would likely only be solid if and only if it was a farm truck used during the spring to fall months... And that assessment is first hand experience.
But always looking to learn better ways... Thanks!
