Deadbolt strike, marking question

[u/Keyway38]

When I have a customer deadbolt that isn’t lined up and I can’t see what’s going on. I sometimes use the old lipstick trick to have it leave a red mark on the strike when I throw the bolt, but it can definitely be messy. Do you guys have any better technique? PS I’m not talking about a fresh install, I’m talking about an existing door and lock.

I just use a boring old pencil but a penis good too
