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.
“Banking institutions have banished precious metals and substituted a more fluctuating and unsafe medium; they have withdrawn capital from useful improvements and employments to nourish idleness for the few, who prefer demoralizing pursuits to labors useful to the whole; the peace of the whole is endangered by evils more easily to be deplored than remedied." by Thomas Jefferson,1810 (edited)
