Being a locksmith perhaps you can tell me if I was right or wrong?Sure, spray in a lock! My work as a locksmith showed different. Tumblers will lock up. Works fine until it dries.
Earlier in this topic I mentioned that the only thing that has happened to the WD-40 since I put a bunch of it into a percussion cap tin lid is that it turned into basically something I would say looks and flows about like 30 or 40 weight motor oil.
I assumed putting 30 or 40 weight motor oil into a tumbler lock could cause the tumblers from moving freely so, the lock wouldn't work.
Was this a correct assumption?
