I used a headlight restoration kit once. It actually made it look worse.

I have not seen the Sylvania kit available in my market, yet have had fair success with the 3M kit; any kit that tries to do the job without multi-stages of decreasing grit sanding, ending in a foam polishing pad/compound will fail. You are literally needing to grind away the oxidized and damaged plastic, often at 1mm or more depth.

These kits do not make plastic headlamps 'like new', yet the 3M kit makes an appreciable improvement. Most would take the tradeoff of a $40 temporary improvement, vs. buying a pair of new halogen lamps from at least $300-400, and especially against needing newer xenon or LED units which can cost thousands of $$ each.
