I've have had cars with spinners for going on ten years (including a Kirkham), and wouldn't consider NOT using antiseize. Every once-in-a-while, I'll get one that is particularly difficult to get off...but never as bad as you describe. I would definitely make sure that you coat every surface that will contact the hub, not just the splined area.

I don't know about anybody else, but occasionally I'll "wet down" the AS a little with WD40 if it looks like its drying out a bit (I reapply if needed). And yes, I use the grey stuff.
