Headlight Restoration on 2009 Mercedes E320

[FrankS]

Headlight restoration on a 2009 Mercedes E320.











The factory coating has begun to fail. In order to restore, the factory coating will be removed by sanding and then the sanding marks will be refined and removed.



This is after using 320 grit sanding discs (dry). All the factory coating has been removed. Double layer of tape to protect surrounding paint.



This is after using 500 grit sanding discs (dry) to refine the 320 grit marks.



This is after using 800 grit sanding discs (dry) to refine the 500 grit marks.



This is after using 1000 grit sanding discs (wet) to refine the 800 grit marks. Clarity being restored.



This is after using 2000 grit sanding disc (wet) to refine the 1000 grit marks.



Griots Garage Mini Polisher was used for the entire process.



This is after using 3000 grit sanding disc (wet) to refine the 2000 grit marks. Almost there.



This is after using McKee's compound and purple foamed wool 3" pad.



This is after using McKee's polish and 3.5" LC ThinPro white polishing pad.



Thin pads help give the GG Mini good rotation.



The headlights were coated with Wolfgang coating.

Forgot to take the final shots but they looked the same as after the polishing step.

Looks very nice and a quality job that will last.

Headlight restorations are one of my favorite things because you sand it down and think "did I just destroy this??" and then you slowly bring it back to 'as new'. It's the biggest transformation I know of in detailing.

I restored my headlights a month ago and started with a small palm sander and 320 grit pads, then 600 grit. Had to switch to a sanding block after that due to no finer sandpaper that fit my palm sander. Wetsanded with 1000, 1500 and 2000 grit. Then M105/Thinpro Gray and M205/Thinpro White to clean it up. It took several rounds with Meguiars to get it to my liking, but turned out great.

Is it really necessary to go through all of the sanding steps. I have had similar results on our 4runners, bmws, benz', chevy's and many other plastic headlights by using rules uhs or HD speed. No sanding, just about five minutes per headlight and a crystal clear finish. Thanks. Phil

Depends on the severity of the flaws. If you got good results with your method, you probably had pretty minor issues. My headlights weren't too bad but I was going for perfection. But if you ever notice the frosted over headlights on some cars (Dodge Neons are notorious for that) you'd automatically resort to sanding. But it's just like correcting paint. Only do as much work as you need to.

It depends.

If it's just oxidation and then you can probably get away with just polishing.

If the factory coating has failed, then sanding will be required.

Depending on which headlights you're dealing with and how far gone they are will usually dictate whether you can get away with your 5 min. method of simply polishing them to perfection. [IME higher end luxury cars tend to have the most beast headlights to try and simply polish to perfection even if they need minimal correction]

Try and just polish/compound some headlights like this on a BMW...



And there's no way on earth you'll fully succeed. I was able to get this far and this was after 30min. of going at it with Mckee's AIO Headlight Restoring Polish and a 3" Gray Thinpro.



Far from perfect, but improved. But alot of work for the incomplete charge...



Cheaper/ordinary cars tend to be a complete breeze to correct with just a quik polish. At least in my experience with them...

VW Passat:



Took less than a min. with the polisher.



Toyotas = easy
Luxury cars = beast
That's the conclusion I've come to. Lol.
