really is that simple just be carefull not too scratch stantion.
Turn it upside down to prevent any shite dropping inside.
Once wiper seal is popped up the foam-rubbery ring will just slide up stantion, squirt fluid onto the ring all the way around using syringe.
There should be a little indent on fork leg where you can get a small screwdriver under seal, just cover driver with a little sparkys tape or similar
Also when you push wiper seal back in, seat the bit near arch first to make sure its in all the way
