Okay so I have been doing some testing on Fluid Film and two other "protection" products in high density salt water for the past 5 weeks in my garage. Fluid Film is blowing the other two out of the water, but I haven't checked in the last 5 or 6 days, so I guess there is still room for error. I keep seeing everyone post about Mobile One Synthetic and how it has worked for them. My problem with synthetics is by design, they creep. Which makes me worried about using them in my carry piece if I am going to keep it loaded with ammo. Will it creep enough to cause a cartrdige primer not to be ignited? That will be part three of the test. For the next step, I want to test Mobile One against what I presume to be the winner of the straight protection class, Fluid Film, but on something that has two metal moving parts to simulate slide to frame or cylinder to frame motion. Scissors? Two metal blades coated with said product and dunked in the salt water tank? After a week or so, see if they open and close without problem or corrision if corrision starts to build up, how fast until they don't work? Outside of that, I am at a loss without wandering the aisle of home depot in my MacGuyver Jacket looking for something that might apply. Obviously it needs to be steel, because that is the basis for the test, so suggesting some kids cast metal train engine because it has moving parts isn't helping. Anyone have any thoughts?
