Hey all
Just used a 3M lens restoration kit for by rear cabin light as well as my front two headlights. Normal yellow fade etc from sun and time.
The results were amazing - I would say honestly a 90+% improvement. Takes 3 or 4 takes of using various grit sandpaper followed by rubbing compound at end - but really effective.
Will post picks in the morning.
