BMW Headlight Lense Restoration - My Process

The dealer got this BMW as a trade-in on a newer vehicle and the headlights really needed attention! 86,000 highway miles (and it looks like a couple of sandstorms).

I started with 2000 grit and that wasn't removing the pitting, so I switched to 600 grit and wetsanding and that worked. This was followed by a smoothing 2000 grit.



For product/polishing again, I started with an orange cutting pat on the Metabo and Diamondite glass restorer. Not working. So, I broke out the air rotary and a 3" wool pad with Meguiar's 105 compound....man, that worked like a champ. My time to completion dropped dramatically with the small wool/compound process. Finished with a foam pad and 105. I'll go back to the headlights with a pass of polish (Menzerna or 83) and a glaze pad, but they finished just fine.

The wool pad is resting on the bumper in the center of the car.

Nice job on the lenses. I did a 98 528 last week and had similar trouble with the lenses. It seems like they use weaker thinner plastic, and as result they tend to deteriorate more. The little 4inch pads really help though when it comes time to buff out the sanding scratches.

Did you tape the paint surrounding the headlight, just to be safe?



No (except for the headlight washers which need protection when I compound the bumper). With the hood raised, the only paint is the trim at the bottom of the light and the fender edge. Using the 3" pad and reasonable care near those 2 areas prevents any burn.

Most BMWs have just general hazing, as opposed to the severe pitting on that car.



For the haziness, Meg's PlastX works great!



It keeps my 10-year-old Bimmer's lights nice and clear:

The boys at Baron must love you. ;) Very creative solution.



Baron can't afford me LOL! They use a "lowest bidder" detail service and I typically take 2 days on a Bimmer....they do 2 cars per day (just the opposite and their work shows too)

Deja Vu !! :) Where have I seen this before ;) I'm tempted to run down to the auto show at Bartle Hall tonight and see just how swirly the cars in their exhibit look!
