A lot of people may think they don’t because of the give, but i hand sharpen my own knives with a convex edge, and these make a great strop. Either one will take a knife and even out the bevel, give it a nice smooth appearance, cover up most irregularities from hand sharpening, and basically give a great base to strop higher for a mirror polish, or leave it as it is for kitchen or bushcraft knives that like to have a little more ‘bite’ to their edge. I am going to buy more, and find a waterproof way to mount them on a base so i can properly use their whole surface. These are silicon carbide, so they cut most every kind of steel, though it is best to keep them wet when using, and they polish things up to a perfect degree for their grit rating. I couldn’t be happier and the price makes these things amazing. I have stropped 7 knives all at least twice, and i just have a little bit of marking on the sheet. Note: if you bend, move, or generally use these things as sandpaper, they will load up. I blame the opening of the sponge material beneath one rounding opening up spaces between the trizact particles, but it is just a guess. If you plan on using these as strops, always use them flat and rinse them. Otherwise, these are great for convex edges, and light on flat grinds.
My application is automotive urethane clear coat, a very tough surface that needs leveling, then polish. I was looking for something to fill the gap between the fine grit papers and the course slurries. This p3000 foam pad works good after 1500 grit paper, but before 2000 grit and therefore my 2000 paper has been obsoleted. After p3000 i start in with 3m super duty rubbing on a cutting pad driven by the pc da. After trying many alternative approaches, this is was found to be the quickest method to transition from scratch removal to polishing. One pad has lasted an entire car project. – precise grit, whereas i’ve found the 3m papers to have occasional course grains sneeking into a fine grit field. – uniform result, whereas i’ve found the 3m papers to vary the grit across the width of the paper.
There are two methods often recommended for getting the gunk off of glass shower doors. The first involves boiling vinegar. If i did not succumb to asphyxia that would be a trip to the er and then a burn unit. The second involves citrus; using lemon juice to remove the build-up. Using this sand paper is pretty effortless. Just keep it well lubricated with water. This will also polish out the little scratches from attempts with more abrasive methods.
I used this 3000 grit, along with a 5000 grit, to remove some scratches from my 2017 malibu and 2014 silverado. As you can see in the photos, i was able to make scratches caused from the magnetic base of a cb antenna completely disappear and restore the clear coat. This was accomplished by spraying soapy water onto the area before sanding (aka: wet-sand). After clearing those scratches from the trunk of the car, i moved to my silverado which had brush scratches everywhere. I was able to wet-sand and polish away every scratch on every panel of the truck and only wore out about 1/4 of the 3000 grit sandpaper, and the 5000 grit sandpaper didn’t show any wear at all. Very good product for the price you pay. I will also add a final note that the sandpaper was not the last step in this process. You will need a scratch remover and polish to finish the job.
Many people complain of automotive clear coat spray’s being dull. If lucky, sometimes spraying clear coat alone does produce wet-look, but usually it has to be polished to achieve the factory finish. I use 3m’s headlight renewal system when polishing clear coat. This item comes with backing that sticks onto 3m’s rotary disc. I first sand dried clear coat with 3000-grit, then 5000-grit and finish with rubbing/polishing compound. The end result is remarkable.
I wasn’t exactly sure on what i needed, so i got the multi pack, and it worked great. I wanted to lightly sand some rust spots on my car (thank you east coast) and this was a great product. It’s 3m, so the packaging is perfect, and the product is the quality you would expect. It worked great to lightly and carefully sand the rust so i could then touch up the paint and keep my seasoned car looking good. To be clear, this is just the sandpaper, i purchased the oem paint from the dealer. 🙂 the multiple different weights were handy as i had to tackle different level and sizes of rust around the car. Very pleased with this purchase.
- A must have in my neighborhood!
- Removed Clear Coat Scratches -see process used
- Quickly removes scale from glass shower doors
Great price for the assortment. Only thing i would change would be to have a 3k grit sheet in there also instead of 2 each of the 2k, this would make it the perfect assortment. I used this to polish my hazed over car headlamps along with the novus 7100 plastic polish kit. Also amazon needs to rethink just tossing this stuff in the box since the outermost exposed sheet in my order was heavily scuffed up and mostly unusable.
I purchased this package of sandpaper, actually 3 packages, for an assortment of projects. I am currently using to wet sand a newly painted part on my vehicle and my second project was to sharpen my chisels, planer and jointer knives. This package is the perfect assortment to complete the task and the price is very reasonable.
A must have in my neighborhood. I live in south florida, people can’t seem to comprehend driving or parking without hitting you car. Literally, i wake up once a week to another scratch in my truck. This 5000 grit along with the 3000 make simple work of fine scratches. Although if you are using something like meguiar’s ultimate compound you might be able to skip the 5000 grit. I use it anyway even if it’s overkill. I reconditioned vehicles for a decade, i wish i had these in the early 90’s. If you have a scratch wet it, if it disappears while wet that is a good indication it’s just in the clear coat and this paper will do the job. Use a good lubricant or soap spray, i personally like meguiar’s waterless wash. Horizontal scratches use a vertical motion and vise versa.
Used to polish hard water and soap scum stains off of my glass shower. Renters apparently didn’t know how to clean things and so nearly 10 years of buildup on my glass shower enclosure resisted every kind of chemical assault. However, 15 minutes with 1 piece of this sandpaper had it looking nearly new – and no fumes.
I don’t know of a better supplier of high grit wet/dry sandpaper. I squeezed out 3+ sets of headlights with one pack. Really think 2 sets is a more reasonable target. I’ve bought multiple packs over the years, i should really look into whether a better brand exists, but like i said, i’m really quite satisfied with these.

About Our Trizact Abrasives For more predictable finishes and improved, consistent quality, 3M Trizact products feature microreplication – small 3-dimensional structures are reproduced and then uniformly distributed over the surface of the abrasive. These patterned, precise mineral is exposed. The result is that the abrasive cuts faster, allows for precise finish control, and stays sharper structures contain multiple layers of abrasive mineral. As the structures wear, fresh, sharp mineral longer, meaning you use fewer sandpaper sheets and save money as well as time.

Use these for polishing knife blades to a stupid level of sharpness, also looks pretty once things are all shiny. Additionally, a knife with a good polish is far less likely to rust due to how fine the microscopic pits are, this also helps with maintaining and cleaning the blade.
Plenty of material to do several sets of headlights. – 800, 1000, 1200, 1500, 2000, 2500, 3000- 5000 (trizact)- compound with some pressure a few times- polish a few times- seal with a good paint sealant (or clearcoat paint).
If you are cutting and buffing, or color sanding and not using the trizact system you are not only missing out, you’re working way to hard. If i have minimal peel i go 1500, 3000, 5000 trizact and buffing with ultimate compound takes a few minutes with amazing results. If peel is bad, 1000-1200 3m auto wet/dry before above and you will thank me.
I used 3000 and 5000 grit sandpaper to remove the scratch on my new car and it worked great. Now it almost looks like there was never a scratch. Though you have to be patient not to burn through the clear coat if you are using this to remove clear coat scratch or scuff on your car. The surface of this sandpaper feels much softer than i thought but few rubbing will start to remove your clear coat.
3m trizact is the best product to come along in a very long time, it makes color sanding effortless and i use these grits to polish stainless steel sculptures and it reduces buffing time by over 70%. Expensive but its worth it in the end. I have plenty of stock of trizact in my workshop. Tried other stuff by norton and mirka but 3m is the best version hands down i feel.

I bought this (along with some 3 inch by 9 inch flat tiles and an adhesive spray number 77) to sharpen my kitchen knives. With a steady hand i have sharpened my knives. I ask my wife to tell me how sharp they are now over and over until she compliments my work.
This package of sandpaper was exactly what i needed to fix a small chip in my hood. I filled it in with some touch-up paint and let it dry before wet-sanding and finally buffing out the scratches. Advice: i would advise against doing this kind of repair for a metallic multi-tone paint. Wet-sanding for touch-up paint works best for flat even colors like white and black. Any metallic colored paints or paints with sparkle in it may be noticeable.
