Clean the lens with soap and water then after drying, tape off the area around the lens. With the power disconnected, mount the backup pad onto the drill.Follow the drill manufacturer instructions to properly attach the backup pad securely into the drill. Attach and center the P500 grit gold-colored abrasive disc to the backup pad.


Using medium to light pressure begin sanding to remove the yellow in its surface defects from the lens. A slow and steady back fourth action will be most effective. When the disc is clogged or no longer sanding effectively replace it with a new P500 grit disc. 


Some notes about drilling. 

Do NOT use excessive pressure down on the drill or the headlight lens. Do NOT hold the drill in one place while sanding this can cause the lens surface to heat up and smear becoming difficult to remove. Hold the drill flat or at a very slight angle and control the drill by using a slow steady speed across the lens.


Wipe off the lens and inspect it to ensure all the yellowing and defects have been completely removed. If yellowing defects or portions of the surface coding still exist continue sanding with P500 grit discs until they are completely removed. The lens should have a white evenly sanded surface that appears to look frosted. If any portion looks clear or glossy continue sanding it before moving to the next step.


Remove the P500 disc. Attach and center a P800 grit abrasive disc to the backup pad. These are the white sanding discs with purple printing on the back. Begin sanding using the same light to medium pressure as before making several passes over the entire lens to be sure that the P500 grit scratches from the previous step are reduced to P800 scratchs. Wipe the lens noticing if the scratches are finer, if coarse scratches are still visible continue sanding with the P800 until the coarse scratches are reduced.


Remove the P800 disc and apply the P3000 Trizact™ Foam Disc. This is the thin foam disc that looks green or grey in colour. Dampen the lens and the P3000 Trizact™ Foam Disc with the water bottle and then using the same light to medium pressure as before sand the surface to reduce the P800 scratches to P3000 scratches. Add a mist of water if the surface becomes dry while sanding. A white residual or slurry will build up on the lens indicating that you are reducing the sand scratches. Continue with 4 to 6 passes over the lens after you see white slurry, if you’re not seeing the slurry make 10 to 12 passes on the lens.


Extra sanding will make the next step easier and improve the final clarity of the headlight. Wipe the lens noticing if the scratches are finer and the lens appears clear. If coarse scratches are still visible mist the area with water and continue sending with the P3000 disc until the coarse scratches are reduced. It’s now time to polish the lens. Remove the P3000 foam disc from the drill and attach the orange foam compounding pad. Dispense a dime size amount of 3M™ Headlight Lens Polish onto the compounding pad and smear the polish with the foam pad around the lens before turning the drill on to reduce splatter.


Holding the drill flat polish the lens until the cloudy haze is gone and the clarity is significantly improved. If additional clarity is needed or desired add another dime-sized amount of 3M™ Headlight Lens Polish to the compounding pad and continue buffing. Remove the masking tape and wipe the lens clean with a 3M™ Microfibre Detail Cloth. Wash any residual spatter from the vehicle using car wash soap in a clean soft cloth.
