Thanks Danny, never thought of a Dremel tool. I pictured myself using a file and inevitably scratching the hood.
MTI makes a good point - I think I'll reconsider my desire to booby trap the star. I can remember doing some pretty stupid things myself in my younger, more misguided days, and it's not worth severing some idiot kid's tendon just to protect a $25 part. Even worse, what about a tech or the innocent guy at the shop shining it up for me before returning it?
