hey i read the other post but it only helped with half my problem

i was wondering how i would go about getting a cracked mirror finish on my guitar
and i dont want any comments saying 'why would you want that?'

the only way i could see doing that is first laying you guitar on it and trace the outline onto the glass. the score the class (i think thats what its called) with the out line. break that glass around it so you have your guitar shaped glass peice. then score the glass again all over the body so they are clean breaks.

like i said this is how i would do it, i could be wrong on how its done though.
