I'm nearly through my first gallon, and alot of that is with a harshly vibrating RTR motor(couldn't wait to drive it, but now I have the Top 3-port in it), and my shock shafts are fine. The trick seems to be to build them with blue lock-tite, and let them dry, overnight, or 24 hours. That way, when you submerge them in oil, they still hold.
