Well I guess the water content hasn't matter with the Loctiite brand I use. Like I said, that stuff never comes off. But it is made by Loctite, so I expect it to be good. For performance to cost, I still think its better than the hobbyshop stuff.
Anyway, I noticed today that my pinion is still fully engaged with the spur even though I had to move it over a little. So I wont even bother swapping the batter bar at that point on the pack.
