I used it very extensively on wheel axles, hub cones, BB cups, and freewheel threadings when rebuilding my friend's two Witcombs. Used carefully, it's a great way to "subtract" the distorted metal which prevents threads from interleaving. When the damage was done the possibility of a full strength joint was reduced, but with the ability to join restored, a lot of bikes can be good enough.
Yep, no worries.
I like to use the scribeing method or chasers first, they can push the displaced material back in place and it will fill the the void closer to what it was and stay that way if we properly clean and tighten it as well as using some thread locker, red at least or SG.
