Recently, I wrote about Adam Savage restoring the yellowed plastic cover of a vintage Nagra IV-S audio recorder. He ended up using a combination of hydrogen-peroxide and a polishing compound to bring the cover back to its former glory.
In the video, he uses a Proxxon motorized angle polisher to restore the faded and scratched plastic dome on a spacesuit helmet while extolling the virtues of the tool.
