Pretty marked improvement - oxidation haze is completely gone. Half dozen grits of wet sand paper ranging from 200 - 2000 grit, a lot of elbow grease (four passes of each grit alternating diagonal directions), and a very powerful porter cable random orbital buffer with a cutting pad and plastix specialized plastic polish. I didn't use the 3M headlight restoration kit for the sanding since my power drill only does 750 rpm and you need one that does between 1200-1500 rpm. Took about two hours to do this one. Doing the other one tonight. Might do the fog lenses but they are pitted not hazy so not sure of it will help might just buy new ones. Going to protect it all with light smoke vinyl covers to match the rear LED Spyders I have.
