I did it a few times with toothpaste as a compound.
Then I did it dry - spin for 30 seconds on medium speed, then SLIGHTLY pinch the ball cup. This warms the ball cup itself, and allows it to form to the ball stud.
The dry method has held up much better, and since I'm using titanium studs, I don't want to mess with trying to wear them out.
