LOL i used a
kit I bought from Auto Zone for 20 bucks that included a bunch of sanding discs, polishing compound, and a disc that could be put into a drill bit. Elbow grease? I'm too lazy for that so long as there's electricity to run my Ryobi drill!
I have to admit though, that is a great result for little money.
Christ, you're showing your apparent age. Laser discs? That's starting to go the way of phonograph records!
