3M EX Ultrafine Machine Polish, 39062, 1 pt(16 fl oz/473 mL

I have tested many products for polishing the paint on cars and I have found none better than 3M. This Ultra Fine polish is for the final step in bringing paint to its ultimate shine. When properly machine applied this polish will elevate the gloss to its maximum level. It is capable of removing fine halos and swirl marks but not intended as a cutter. Highly recommended.

If you have black paint and are buffing and getting paint corrected you already know the risk of seeing buffing swirls after finishing. Not with this stuff! Absolutely zero swirls, easy to manipulate, low sling. I suggest getting a black hex pad to go with it and this is the perfect last step in paint correction.

I have been looking for a good polish for my resin work for a long time. This three-part system beats everything I've tried hands down. I got to give it to 3M, they have the pockets to do a lot of research and it's paid off. I've held off buying this because of the cost, but out of frustration from other products I finally decided I would give it a try. It doesn't take much if you have a good orbital polisher but the results are stunning. Get all three products if you're planning on using this, you won't be disappointed.

I would say that this probably wont remove any scratches at all, but refine the finish after #2. Step 2 removed light scratches, this made the paint feel slick after and left a deeper shine than 2. Definitely a very fine compound that doesn't leave any swirl marks. Easy to work and clean up.

Great product. Had to return. No longer needed

I have mostly used Meguiars polishes and machine glazes, which I think are some of the best because of the rich, smooth paint feeling they produce. Their customer service is repulsive & rude, however. The last batch I used was defective, though I didn't know that thinking they had changed their formula. So I tried 3M. I think it doesn't produce the creamy paint feeling like Meguiars and it feels a little more "dry" when applied with my polisher--I have a feeling this product is more for auto body shops, where the polish product needs to be less aggressive. Will use it up and make a return attempt to Meguiars.

I'm not an experienced auto detailer, and wanted to get rid of some light swirl marks left by a clay bar. I bought the three-bottle 3M Perfect-It system, a Porter-Cable DA polisher, Hex Logic pads, and Chemical Guys microfiber. The #2 polish works like a conventional liquid polish -- it leaves white dust, cleans up with medium difficulty, and leaves black paint hazy, but mostly swirl-free. This #3 polish is really a great way to finish the job. It leaves no swirls, holograms, or anything, and wipes up dust-free in just a few passes. It's rare that a product works better than expected!

I use this as a final step to polish any remaining swirl marks from buffing with a medium compound. It does a great job of adding depth and mirror finish to black paint. The buffing process is easy and works best as the pad becomes slightly heated so the oils in the polish can work as a lubricant.
