Thanks for the tip, will use it when I need to restore the rim.

Not meaning to divert this thread, those cuts can be repaired to present a better finished rim before final painting.

While naturally a bead of weld will fill the grooves, the weld itself will require further grinding to clean it up flush and present a smooth lug nut seat. Some people might also have qualms about heat damage from the weld affecting the temper of the rim, and therefore it's structural soundness.

I have had great success with a metal filling epoxy called JB Weld. It can be shaped, sanded, or ground easily and binds securely to metal, so won't fall off in a slab years later. Readily painted with any automotive primer and paint system (ie Enamel or Acrylic). It doesn't just work on repairing grind marks, it also does a fantastic job on sandblasted rims that have hollows from rust pitting or gouges from kerb strikes. You'll have that rim looking like new again.
