Ok here is the scoop.
The corroded nail is the Yamalube. The finely pitted nail (right side) is the TSI. Yes the Yamalube is the marine version (dark blue before they changed the formulation to pale blue). The Yamalube nails were rolled between the fingers with Yamalube trying to force good adhesion to the nails (3 of them). The thickness of the Yamalube varied from a thin layer to thick enough to stick the nails together. Keep in mind that this test was with plain old iron that will rust in the rain.
Here is what I think is happening here.
The corroded nail still has some areas that did not corrode. I think the Yamalube stayed in place. In the other corroded areas it looks like the corrosion undermined the yamalube. Remember this is a 6 month test. Plenty of time for corrosion to go under the protective layer.
In simple terms any pinhole through the lube will corrode and corrosion can migrate under the Yamalube since Yamalube does not flow.
The TSI will flow and spread to cover the metal 100% inside and out like water in a sponge. Also it will not allow corrosion to undermine and any corrosion will be forced free and undermined by the TSI
There was free rust staining in the water with the TSI with only a film of sludgy rusty like paste with the TSI. The Yamalube had growths of rusty paste 3 or 4 times the diameter of the nails indicating the rust once formed stayed in place.
Too bad TSI is not compatible with grease.
Short term test with SS bearing showed no rust at all with TSI. Howerver salt crystals can form around the balls seizing the bearings until rinsed in fresh water or the bearing is forced to turn breaking the crystals apart. If there was grease there would be no salt crystals as the grease would occupy the space.
