The Aussie experts know best (again!).
I also prefer teflon (thread) tape. Cheap, easy to apply, and effective; and it is easy to break the seal when removing the seal holder.
Don't forget that there is a right or wrong way to apply PTFE tape; it needs to be wound ont the thread in the same direction as the fork seal holder (or fitting) screws, to avoid it being damaged (torn up) when installing.
Another application I use thread tape for, is to more effectively seal the oil inspection cap, and the primary case cap.
Make the tape narrow by doubling it over on itself, and put two turns on the cap thread.
This seems to make the caps seal, and keep the oil mist inside the tank, and engine.
