what MOST people forget..
and why the new seals leak..
YOU MUST PREP THE FORK TUBE.
there is a reason your seal is leaking.. is the tube scratched ? pitted ??
what ever.. who cares.. the point is 99% DONT polish the tube with 0000 steal wool.. and forget use condoms on the fork,
yes, you read that right..
put a condom on the end you plan on sliding the seal. ..
it will protect the lip of the seal past sharp edges and clamp marked areas.
slide on seal.. cut of tip of condom.. slide to the seals operating area.. snip condom as close to seal as possible, and remove rest from seal.
