Good tip K!
Since I'm in the thread...for those who repair/rebuild older bikes with lots of loose bearings and stuff, a syringe works great for precise grease application. Easier than big grease gun or loose tub of grease. Pack the syringe (an old EPO syringe would probably suffice - but I use a larger one - 10ml or so), and you're set.
Also, old bar tape makes good chainstay protection for your MTB.
