Chrome Nut Removal

[highship]

What is the best way or tool to remove the head set nut and the crank nut without scratching them. Especialy if they are stuck?
Thanks for the help.

Vice Grips! Oh wait! Without scratching them? I have no clue.

Painters tape will help. Otherwise, using the right tool will help.
