I only noticed the differenct when changing to the BLACK Lube from the GREEN Lube. Otherwise I wouldn't have known. I liked how nice and longer the BLACK has lasted and how much water was kept out of the system especially when changing out brakes and lubing the sliders after a long winter.
Often while rotating my tires on the car, I like to sometimes bleed the brake system and check out the brakes/rotors for ware along with relubing the sliders and the brake pad backing(shim side of course).
The Permatex BLACK with the RED Label as compared to the GREEN with the GREEN label, seems to withstand moisture and road salt much better than the Green lube does in my experience. Parts seem to move more freely and for a longer period of time, much better with the BLACK(actually it's dark gray) but, you get my point!
When using the GREEN in the past, each time I would replace brakes or brakes/rotors, 1, 2 or more sliders would bind up/stick more often with the GREEN and I don't seem to have these issues with the BLACK lube at all!
Now, I'd really like to try the Syn-Glyde to see if it's even better still! So, those who live in the salt belt of winter, are the responces that I'm looking to read.
