A. Remove lens yellowing and defects using a 3” Sanding Tool
- Clean lens with soap and water. Then, protect adjacent areas around the
headlight lens with 3M masking products. - Identify and use the tool labeled “SANDER” for Steps 3-10. Attach the 3M™ Hookit™ II Soft Interface Pad (PN 05271) to the 3” SANDER.
- Attach a P800 grit disc (PN 00710) to the 3” sanding tool equipped with the soft interface pad.
- NOTE: For heavily oxidized and pitted lenses, it may be necessary to start with a P500 grit disc (PN 00712) followed by a P800 grit disc.
- Begin sanding to remove yellowing and surface defects from the lens. When the disc is loaded or no longer sanding effectively, replace it with a new P800 disc and sand until yellowing/haze is completely removed*.
- Wipe off the lens to ensure all yellowing and defects have been completely removed. If the yellowing or defects still exist then continue sanding until they are completely removed.
*If the P800 disc is loading too quickly or if the yellowed surface is extremely hard to remove, sand using a P500 grit disc followed by the P800 disc.
B. Refine the lens surface using a 3” sanding tool
- Continue using the same “SANDER” tool. Remove the P800 grit disc and attach a 3M™ Trizact™ P1000 grit foam disc (PN 02068) to the soft interface pad.
- Using a spray bottle, apply enough water to dampen the foam disc before sanding. Begin refining the lens with the damp 3M™ Trizact™ P1000 foam disc. A white residual will build upon the lens indicating you are removing the P800 grit scratches. Add a mist of water if the surface becomes dry. Avoid sharp edges or alignment pins on the lenses to further extend the life of the foam abrasive discs.
- Wipe the lens, you will notice the scratches are finer and the lens will
appear cloudy. - Remove the P1000 grit foam disc and attach a 3M™ Trizact™ P3000 grit foam disc (PN 02077) to the soft interface pad.
- Continue refining the lens further using a 3M™ Trizact™ P3000 foam disc.
Remember to use a mist of water on the gray foam discs to yield the best results. Again, the white residual will indicate you are refining the lens. - Wipe the lens, the scratches will be finer but the lens will remain somewhat cloudy.
C. Polish the lens using a 3” polishing tool
- Identify and use the tool labeled “POLISHER” for Steps 12-18. Attach the white foam compounding pad (PN 05721) to the 3” polishing tool.
- Dispense a dime-size amount of 3M™ Plastic Cleaner (PN 39017) to the white foam compounding pad. Too much 3M™ Plastic Cleaner will result in an excessive sling and added clean up. Do not run the foam pad dry.
- Buff the lens until the cloudy haze is gone and the clarity is significantly improved. If additional clarity is needed, add another dime-size amount of 3M™ Plastic Cleaner and continue buffing.
- Wipe the lens and remove the white foam pad.
NOTE: For body shop users, if products that contain silicone are a concern, stop after step 15. If not, proceed to the final polishing step in 16. - Continue using the same “POLISHER” tool. Attach the black foam polishing pad (PN 05722) to the 3” polishing tool
- Dispense a dime-size amount of 3M™ Plastic Polish (PN 39010) to the black foam polishing pad.
- Polish the lens using the black foam polishing pad and 3M™ Plastic Polish
- Wipe the lens clean with a soft cloth or 3M™ Detailing Cloth.
