[Closed] RS Lyrik - seized shaft

Has anyone ever had the shaft seize into the lowers of their RS forks?

Went to do the standard lower lube/service, the damping side was fine, but the spring side will not budge when trying to release the shaft. (Usual method of unscrewing the bolt a couple of turns, and giving it a whack with a soft hammer)

I've hit it a fair bit harder that I would like to already, and I'm reluctant to start spraying anti seize in there as there is only a tiny space it could penetrate and I want to use the fork over the coming days and i'm not sure that will be too good for the internals anyway.
The fork is running fine at the moment, it's just due a lower service - last was 10 - 12 months ago.

Any smart ideas out there?

Cheers, CM
