Cheaper than AutoZone, 3M Quality.
A good assortment of quality papers and grits, much cheaper than AutoZone. 3M is known for quality and the papers were durable, staying together for all but the most aggressive jobs, which could use a stronger cloth-based paper.

My first choice
I’m a Big fan of 3M products and when it comes to repairing very small dents or rust on vehicles, this 3M Assorted Sandpaper assortment kit is my first go to choice. The variety of grits, durability, versatility, and reliable performance make it a dependable choice for me of achieving smooth, consistent final results. This sandpaper kit is also great for DIY people who want to learn to repair very small jobs. For the price of $6–$8, it is definitely worth the value for money.

Very good variety for a good price but won’t last
I need to sand some car trim pieces before painting and priming and I purchased this set. It’s pretty good at what it does but the paper is not very strong. It fell apart and was pretty painful to try to make it work. Nevertheless it did do its job but if I was buying again, I would give another brand a try.

Works perfectly for sanding aluminum parts for paint prep
Used for prepping D16 Valve Cover, loops great. Will eventually use it to sand through the grits over lettering to make the part pop
