DISC SURFACE PREP 2IN COURSE 25BOX

not quite the quality as 3M, but much less costly and last almost as long.

I had left a previous review on these discs once before but after using them in my shop for a few months I have really found that these things are absolutely priceless. they make gasket removal extremely quick and painless. One thing to remember though, if you are goigng to use these on aluminum parts. DO NOT USE THEM DRY. they will completely destroy your mating surface. that being said, a little mototr oil on the disc combined with a little finesse, they will do the job just right without taking any metal with them. clean up the surface with a little solvent of your choice and you will impress even yourself.Good luck everyone. hope this helped a little bit.

High quality pads but very abrasive so be aware when ordering. The Medium is still too coarse for cleaning aluminum surfaces but the Fine disks (IIT 82070 Fine 2-Inch) leave the surface shiny & clean without grinding material away. The Coarse is perfect for cleaning rusted steel surfaces and other corroded materials.

Use them for cleaning gasket any grime off a metal they're awesome

These things a defiantly worth it for the price. My only complaint is that I tend to burn through rather quickly, however, that make be because I need to turn down the speed on my grinder

Been using these for years and almost as good as 3m ..25 for per box for 28.00 dollars, can't beat them!!

These work great and are a lot less than other manufactures.

I've used the Mountain prep disc for 4 years at my automotive shop. The quality is very good with the lowest pricing I've found. I've had no problems with packaging. Delivery has always been on time or ahead of schedule.
