The Park Tool web-site (http://www.parktool.com/repair_help/FAQcartdg.shtml) suggests using anti-seize for installation into an aluminum frame (which this is).

What is the recommendation of the mechanics here? It somehow seems scary to tighten something to 70Nm without any lubrication on the threads. If I lock-tite the thing in place, will it ever come out again? What's the difference between anti-seize and grease anyway?
