I have a left fork seal leaking. It only has 30k miles and in a climate controlled garage. I accidently discovered something called Sealmate which is nothing more than a piece of thin plastic to clean the seal. I think back and years ago I had a bike with a fork leaking and out of the blue it quit! I asked a mechanic and he said they do that sometime. Maybe I'll get lucky and not have to buy seals. I guess that piece of grit or whatever worked its way out and stopped the leak.
