don't want to break the spirit, but it looks extremely hard to do... check out the JEM site (JS section), one guy did it, but he's a serious expert in this field. The chrome spray + clear coat is worth a try, but if it was that easy Ibanez wouldn't be having such a trouble releasing a chrome guitar.
For info, they released 3 version of the chrome JS : first for joe himself (the chrome is breaking apart after few years), second : the body is not wood but luthite, third, the finish is quite fragile (still, it seems to be the most reliable one so far)
well, maybe i mixed some of the chrome JS story, you can look it up for yourself

i wanted a chrome guitar too, but finally, i'd rather have some funky painting : the chrome is only for seriously talented people
