My cruiser fork seal started to leak in 2004, with only 3,000 miles on the bike.
I used the same cleaning method, but with a piece of old 35mm film negative cut to the same shape, and a thick paper business card cut to this shape also works.
This fork seal is still not leaking after 8 years and about 23,000 more miles.
"We have created a Star Wars civilization, with Stone Age emotions, medieval institutions, and godlike technology. We thrash about. We are terribly confused by the mere fact of our existence, and a danger to ourselves and to the rest of life.”
― from Edward O. Wilson, The Social Conquest of Earth.
