Mike, I couldn't find a 3M package that had the 3000 grit, but, this would only work as a final pad. We have also found that even with the 1000 grit paper as the final pad, the minor scratches that are left turn almost 100% invisible once you apply the 3M wipes.
On my Marquis, I ended up replacing my headlights a year after I cleaned them since they had someplace they were getting moisture in one of them even after applying a sealant to the O-Rings. The new ones I ordered where the smoke color that look great. The only downside is they eat some of the light and I had to go to LED bulbs to overcome the tint. While I am thrilled with them now it was a chore to get the alignment perfect after replace the bulbs with LEDs.
Regards,
Al
