People use graphite based lube on car locks to keep them from freezing.. Still not come across any on my wanders though, so can't comment on its effectiveness..
Nooooooooooo the WD stuff leaves a nasty film which attracts crud and then jams the lock. have seen some sectioned locks in work that were cut off after WD40 ing. the amount of gunk inside was really worrying. If you really want to get rid of the water pop em in an oven at 50Degrees C for an hour or so. then a proper graphite based lock lube from a locksmiths not B&Q or Homebase.Squirt them with lots of WD40 / GT85, which will drive out any water and coat the internals so ice struggles to form in there.
Alternatively, give a squirt from a car windscreen de-icer when you lock them.
That depends what the locks are used for. If it was going to be in a dusty environment (such as, for instance, a lock which is attached to a bike frame for transport) then yes, the film from using WD40 will attract crud and may jam.Nooooooooooo the WD stuff leaves a nasty film which attracts crud and then jams the lock. have seen some sectioned locks in work that were cut off after WD40 ing. the amount of gunk inside was really worrying.
surely a proper oil is all that's needed, proper as in heavy and erm ... oily

However, for a garden shed, then there is little chance of much crud to be flying around and the film will keep the water away, which is, IMO, a good thing.
I saw a bloke on telly t'other night recommending a drop or two of fairy liquid worked in as the preventative cure for frozen car door locks - I assume it would work for padlocks too.
