For those of you that have been following up with my current thread, you know I am having some lock tumbler problems.

Well, I got my new tumbler from MB and it came coated with some vasoline as a lock lubricant. Any thoughts on this?

I have heard that WD-40 is bad because its thin and washes away the graphite, I have heard white lithium grease is the way to go, etc.

I know I tried to use some ATF and ever since I used it, i been having lock problems

What do you guys use for locks?
