Loc tite 242 blue.
Don't use the Loc tite 262 Red . You will never get it back off. I've used allot of the Loc tite products over the years.

Rebel Hog that's the first I ever heard of White Out for that use.

I used the red on a trailer ball once. Big mistake. I had to heat it up and then the impact wrench beat on it for what seemed like ever. I bet it was a good 20 minutes getting it off.
