That is misleading in so many ways!!
It proves that GT85 does not mix with water as well as the 'leading competitor' - whoever that is!
It ignores the fact that if you are going to lift away water and grease from a surface then you have to dissolve or emulsify it! It's similar to the way that detergent works in your dishwasher and when doing the washing up - the 'soap' (WD40) wraps itself around the dirt and water and allows it to 'dissolve' into the WD40 that is flushing it away.
It ignores the fact that WD40 is primarily oil-based with a volatile solvent to carry it to the point of use. The solvent has two uses - to carry away water and dirt and to allow the oil to be delivered to the points of use. Once the solvent has evaporated the oil remains as a guard to prevent corrosion.
The GT85 has PTFE in it, but that is a lubricant, not a corrosion inhibitor. As can be seen from the demonstration, GT85 is not miscible with water, so it can only displace it if it forces its way across the water. In the demo, the leading competitor has emulsified the water and/or dissolved the grease so it is no longer in contact with the metal, whereas the GT85 is sitting on the water which could still be in contact with the metal.
The GT85 you sat your bearings in did not get behind the water in the bearings. As their demonstration shows, the GT85 simply sat on the water which was still in contact with the bearings - as you found out when they came out seized!
Once the GT85 is delivered to the point of use and the PTFE is present, that will act as a barrier to water clinging to metal. We used to use GT85 as the way of preventing water staying in bearings and getting to the metal surfaces, and then WD40 (WD stands for water displacement!) to flush it out before the next race, or to take it home. I hope that helps.
Hotshot - that is just so innovative; top marks!
