Whilst doign some work the other day it occoured to me that I always put some kind of anti-siezing liquid/grease/mixture on any bike part I'm working on.
Why?
Whenever I've bought any new bike the threads have always been dry with a smear of blue threadlock.
Is this an american thing as they don't get rain/mud like we do so they specify things to stick in the frame, where we spec them to come out again when they inevitably need a service much quicker than expected?
From your time working on cars?
IMO no need - grease for all threads, loctite occasionally where needed (pretty rare), no need for coppaslip either (cars of course see more salt and less dissembly.)
