hmmm...I like this idea...I thought about this a while back too, when I saw...what was it?...I think it was either an Illumina or some kinda Oldsmobile or something, and the center light lit up...
I would try soaking the paint with rubbing alcohol, and then using cotton pads to get it off...(won't be easy) It would have to be repeated several times probably, but it would work...I have heard of people doing this with the inside cover if their Mac Laptops, so that you can have a clear cover, and display whatever you want...
