I am running out of a product called gray bolt prep by Fel-Pro. Part no. GRA2
This stuff was the best in my opinion. It is a low strength threadlocker that lubricates and seals any engine bolt. It also has graphite for anti-seize protection. I have been told that Fel-Pro no longer makes these products. I was at the local auto store yesterday and didn't really find anything to take its place. Who makes a substitution?
