Looks like overkill to me...
After priming the ball, I left it almost an hour to get dry to the touch, and I was VERY frustrated to learn that:
1) The spray propellant (or the low temperature, or both) had dissolved/broken the adhesiveness of the LocTite Powerglue (I've never had this happening before), AND
2) that the primer had not yet completely dried and rubbed off on my index finger, leaving a finger print in the surface.
the disastrous priming efforts.
