While wd 40 has some lubrication and rust preventive properties, it is really just what the name stands for: " water displacement formula number 40 ". It is intended to displace water not lubricate or prevent rust though it will do both to some extent. I used to use the old standby G.I. gun oil. But a friend who retired from special forces started me on Three in One Oil and it definitely is a better rust preventive. :idunno: :hmm:
