3M recommends a speed of 1200 to 1600 rpm

Move the drill at a slow steady speed across the lens

The lack of plastic polishing wheel or agent combined with a high speed abrasive lead to a lot of micro scratches that are still visible after the final buffing pad is used

That it requires an electric drill (not battery, as steady, high speed is needed) makes it easy to apply

Use slow speed & light pressure for the first 2 pads.

Slow speeds, light pressure, lost of water, NO gunking up the pad

Set your drill for slow speed setting for best results w\ sanding discs...worked for me.

Use the slow drill speed on every step other than the last few passes with the polishing compound

The only issue is the speed of the drill

Move the drill at a slow steady speed across the lens

We used a slower speed drill but the results were still good.

My drill runs max 2500 rpm and they call for max 1600 rpm, but I simply did not run it full speed, and it worked perfect.

A slower speed works much better, as higher speed drills create more heat and you

If you take your time, your headlights will be a s good as new.

Then I got out my clean, dry, blue shop towel and started to rub off all of the excess compound and holy cr*p
