Check and make sure your fork barrels are not pitted. That will take out a seal pretty quick. You can sand pits out if they're not too bad. Use some super-duper fine paper and it won't harm a thing unless you overdo it or if the pitting is too bad.
I will say, however, my fork seals were bad at about 24,000 miles but the new ones have more than that now and they seem to be doing just fine.
--Wag--
