Man I can't believe all the nonsense about how much too use! LongFemur is right on. It doesn't matter if you use an over abundance of grease on the threads...BECAUSE, the excess grease will just ooze out of the thread anyway and you just wipe it off after your done installing the pedals-big deal!

You can use wax but wax is not as good of a lubricant for ease of installation, and it won't prevent rust from forming over the long haul.
