Review on 3M 39061 Perfect Machine Polish by John Bourgeois

3M manufactures products of the highest quality. You pay a little more and it's harder to find, but you get a professional product. I used this as a final step in restoring some headlights and it works great. If I were a bit more picky I could get an Ultrafine #3 product but not sure if that affects my headlights that much. It's hard to tell if the plastic has internal microcracks from years of exposure to heat and cold or something else. It's only when my xenon headlights shine through the lens that I see the slightest haze inside the lens.
