Well just did the mod finally and sucked but wasn't to bad. My headlights came right apart but I'm an 07 and live in the desert so prob helps. Definitely use bleach!!! Make sure you have a container big enough but not so big it takes 10 gal of bleach. I let each one soak like 30 min and sanding the rest of was cake. Also don't use anything abrasive to clean the inside of the lens as mine are now scratched, I used news paper which works wonders for glass and apparently is like sand paper on plastic...
