What is the difference between a compound and a machine polish?

A compound uses a more aggressive abrasive to remove deeper scratches and oxidation. Machine polish like the 3M 39009 uses a finer abrasive to remove the swirl marks left behind by compounding. It is the refinement step before applying wax or sealant.

Can I use this by hand instead of a machine?

3M labels this as a machine polish, intended for use with a polishing pad on a dual-action or rotary polisher. While small touch-ups by hand may be possible, the product is formulated to work best with machine application.

Why does this product contain no wax or silicone?

Wax and silicone can fill in and hide surface defects rather than removing them. By excluding these fillers, 3M Machine Polish gives you a true correction of the paint surface. What you see after polishing is the actual condition of the clear coat.

Product Details

After compounding, even a careful job can leave swirl marks, especially on dark-colored vehicles where every imperfection catches the light. 3M Machine Polish 39009 is the step that takes those compound marks out and leaves a clean, swirl-free finish ready for wax or sealant.

The formula uses a fine-cutting abrasive that removes compound swirl marks and minor surface defects without leaving haze behind. It contains no waxes or silicones, which matters because those fillers can mask defects temporarily rather than actually correcting them. When you buff this out, what you see is the actual condition of the paint, not a filled-in surface that will show its flaws again after a few washes. 3M designed it to work with their foam polishing pad for the best results, and it is compatible with all paint types and clear coats.

The 16-ounce bottle goes a long way since machine polish is used in small amounts per panel. If you are doing paint correction work, this sits in the lineup between your cutting compound and your finishing wax, handling the middle step that makes the final result look professional.
