I can't decide if I should do it or not. I have pair of first gen plasma/ice juliets SN J1057902, the original lenses are gone, and the frames have seen better days. they are in desperate need of a tune up and I am thinking about tossing them in a vibrating tumbler to try to polish them up before I send them in for a tune up. Would it be a sin to do this to a first gen plasma? or should I quit being a cheap ass and just buy a polished pair?
