I had a plastic case on my Thunderbolt sporting with an extended battery. Nice looking. But the case kept pulling on my screen protector which kept causing it to bubble up or peel back. I had a case because my Tbolt had its housing casing with patches of its paint peeling off. Seeing my wife remove her color off her nails using alcohol, I decided to give it a try. It smoothly removed the paint off (which was glittery) to a more gunmetal paint job. Giving my Tbolt a new bold look. You can also use qtips to remove paint from curvy areas.
Happy new year!
