A. Remove lens yellowing and defects using a 3" sanding tool
B. Refine the lens surface using a 3" sanding tool
Process Steps
1. Clean lens with soap and water. Then, protect adjacent areas around the
headlight lens with 3M masking products.
2. Identify and use the 3M
™
Random Orbital Sander (PN 28353) for Steps 3-10.
Attach the 3M
™
Hookit
™
Soft Interface Pad (PN 05771) to the 3" sander.
3. Attach a P800 grit disc (PN 30260) 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 30272) followed
by a P800 grit disc.
4. Begin sanding to remove yellowing and surface defects from the lens.
When the disc is loaded or no longer sanding effectively, replace with a
new P800 disc and sand until yellowing/haze is completely removed*.
5. 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.
6. Continue using the same 3" sanding tool. Remove the P800 grit disc
and attach a 3M
™
Trizact
™
P1000 grit foam disc (PN 02091) to the soft
interface pad.
7. 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 up on 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.
8. Wipe the lens, you will notice the scratches are finer and the lens will
appear cloudy.
9. Remove the P1000 grit foam disc and attach a 3M
™
Trizact
™
3000 grit
foam disc (PN 02087) to the soft interface pad.
10. Continue refining the lens further using a 3M
™
Trizact
™
3000 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.
11. Wipe the lens, the scratches will be finer but the lens will remain
somewhat cloudy.
