Deffo notto GT85!
Some Finish Line wet lube is the best stuff I have found. Also maybe try using the end of a zip tie to pull back the edge of the seal a little to try to get some down into the seal a bit. As it has been inactive for a few months, maybe turn the bike upside down for a few hours so some of the lower leg oil has a chance to get to the bottom edge of the seal as well.
Do the oil on stantion, cycle fork and wipe thing a few times until there is no gunk in the oily tide mark at all.
Does this mean you will be out and about again in the evenings soon?
Either I’ve got your number or you’ve got mine, so if we make contact I can let you know how we are now organising away from the prying eyes of our local NIMBY puritans…….
