I am finishing building up my 1970 PX-10 and spent most of the afternoon at the bench grinder/buffer. As usual I walked away looking like a coal miner and my workbench is a mess but I am so happy with the results. I have another Stronglight 93 and I really enjoyed the "before and after" pic below. I am all about original paint but I can't resist shining up the metal parts to finish off a build. I would love to hear from any other mirror finish enthusiasts or perhaps from anyone who thinks this is bad form.
