I've been using the gray anti-sieze on my Corvette's knock offs for almost 20 years without any problem. A thin coating is probably best, but it needs to be applied to the pins, the threaded shank and the cone shaped contact portion of the spinner and wheel. Some Corvette knock off adaptors with a paint finish rather than a plated finish (like mine). Even with the anti-sieze coating the paint on the threads can begin to abrade and ball up and foul the threads. That could be one posssible problem.
