[quote=Dogboy]Tef-gel is an anti-corrosion paste. It is good for situations where there is risk of galvanic corrosion due to dissimilar metals in contact (such as stainless steel rivets in aluminum extrusions). It is very good for those applications.
The H18 crossbar bolts don't seize due to corrosion, they are stainless on stainless (where the threads engage). They seize due to galling (essentially microscopic "globs" of stainless steel are sheared off under high pressure and clog up the threads). In this case, you want to use an anti-seize grease which is intended to lubricate the threads and prevent galling. These lubricants are readily available at auto parts stores.
