Review on 🧽 3M Pro Pak Wet/Dry Sanding 600A Grit by Sean Carter

I have been using 3M products in my body shop for about 25 years. I wanted to buy some products online hoping to save money compared to local paint suppliers. I received this pack of sandpaper and upon opening the box I immediately noticed something odd. The sandpaper is gray which is different from all 3M papers I have used before which were black. Also, the 3M logo on the back has black outline writing. Any 3M sandpaper I've used in the past has always had the red 3M logo on it. I was curious to see how well it worked, which was an instant disappointment. It immediately goes from the so-called 600 grit to 2000 grit. Not at all like the 600 grit I'm used to. Trust me, look elsewhere for 3M 600 grit sandpaper.
