The reason fineliner may extend the life of your stylus nib is indirect. The fineliner always has the same thickness regardless of the pressure or angle you press the stylus on the screen. Therefore, you can make the most minimal pressure necessary for the device to register a stroke. This will cause less wear on the stylus nib.

No permanent damage will happen. It's possible the stylus position won't register correctly on some of the screen for a while but usually a restart can fix it.
