DIY Mercedes Headlight Restoration Instructions
Step 1 Start by cleaning the headlight lens with some water. Tape the area around the headlight. Apply two layers of tape in case you accidentally sand the tape.
Step 2 Start sanding your foggy headlights with the 500 grit sandpaper. Continue until your headlights look entirely dull. Even if you had clear areas, you should sand over those areas as well. With the 3M kit, you will have three 500-grid sandpapers for each side. Going through all three sandpaper disks will require time, but this step is crucial.
Step 3 Next, use the 800 grit disk to remove a more cloudy yellow layer from the headlight. Please continue using the disk until it is no longer releasing any oxidation. During this step, you should remove the yellowing and any lens defects. Spend at least 15 min per headlight during this step.
Step 4 Once you are done using the 800 grit, attach the 1000 grit to the sanding pad. Use the spray bottle to apply water to the surface as you sand with the 1000-grit disk. The 1000 disk is a black foam disk. White residual should come off the headlights, and the lenses should start to look clear again. Spend at least 5 minutes with the foam sanding disk for each headlight.
Step 5 The next step is to use the P3000 foam disk. Sand the headlights with the 3000 grit for several minutes. Continue to polish the headlights to remove as many excellent scratches as possible. At this point, the lenses should look better but may still appear cloudy. You may notice minor scratches if you look closely at the headlight.
Step 6 The last step is to clean the headlight lens with a clean and dry cloth. Place a small amount of the rubbing compound on the polishing disk. Buff the headlights until they look crystal clear. This allows the headlight to be sealed and makes them look new again. If they don’t look clear, apply some more rubbing compound on the disk and continue to buff the headlight. Once the headlight starts to look clear, use a clean cloth to clean the headlight. Remove the tape from the car, and you are done!
The final results depend significantly on the kit you are using and following the proper instructions. That’s why it is essential to use a high-quality headlight restoration kit. Most kits sell in the $20 range. This job is labor intensive, so don’t go through this process using cheap equipment.
Once you are done cleaning the headlights of your Mercedes-Benz, you will have a big smile and no longer be impressed by the foggy headlights.
