3MWetordry Sandpaper, 03022, 800 Grit, 3 2/3 in x 9 in, 5 Sheets Per Pack

I'm not sure what 3M was thinking? I bought two packages and both had damaged top sheets from transport. This is great sandpaper but they're not cheap either. It's especially disappointing since this is fine and meant for a final step.

Worked and held up well.

Excellent product

Did the job

Great product. Marked way up.

Good quality sand paper that I’m using to sharpen hand plane irons.

Very well performed as described in ads

If you're a parent of a cub scout who does Pinewood Derby cars every year, you'll want to pick up a set of this wet/dry sandpaper. It's a nice collection of just the right grit to polish the car's axles for greatest performance. The axles (nails) that come in the box with the pinewood derby car have burrs and crimp marks on them that lead to unnecessary friction between axle and wheel. Friction is the enemy of speed so it's best to file these down, then polish the axles using this fine grit sandpaper to get a smooth finish, with much less friction between the axle and the wheel.Ideally you'll want to use a power drill, clamped into a vise, with the axle securely inserted into the drill head where a bit would normally go. Get yourself a fine tooth metal file plus a sheet of 500 or 600 grit sandpaper as well (not included in this set). Cut the 500 grit paper, plus each of the strips in this set into a few strips about 1/3 inch wide. I find it's best to mark the back of the paper in 1/3 inch increments and write down the grit number in each 1/3 inch section using a sharpie (e.g., 1000, 1500, etc.). This allows you to keep each strip straight. Also, be sure to wear protective eyewear and a dust mask to keep any metal dust or filings out of your eyes and lungs. Then it's pretty simple:* secure the axle into the drill head with a little over 1/2 inch of axle exposed* make sure drill is secure in vice* start spinning drill* use metal file to remove burrs and crimp marks (careful here not to file more than needed)* stop drill and inspect axle to make sure imperfections are gone. Surface of axle should now be smooth but with fine scratches* restart drill* using the previously cut 1/3 inch wide strips, polish the axle (including inside of head) starting with 500 grit sandpaper, moving up to 1000, 1500, 2000 and finally 2500.I find about 15-20 seconds with each grit works pretty well. The sandpaper holds together well wet or dry. Also, a single strip is usually good for two or three axles so a little sandpaper goes a long way. Put the unused paper into the pinewood derby box for next year (this is why labeling the individual strips of sandpaper is so important).Be sure to inspect each axle (preferably with a magnifying glass) after you're done to make sure it is smooth and shiny. Some people continue the polish out to even higher grits (3000+) but I've found that 2500 grit works well. Using this technique, my son has been able to take home a few trophies for his pack and district derbies. I realize this may not apply to all prospective buyers of this sandpaper, but hopefully it's helpful to some!

So far this one has the greatest durability

Was recommended for use on a scratched mobile screen made it worse. Don't use for that.

A must have for a guitar painting enthusiast

Quality

Worked well to wet sand my truck hood. Pleased 😀
