I've owned a body shop for 48 years, I'm close to retiring and sure wish I would have found this product years ago. I've never seen a 24 grit that could keep its edge & bite on Dyna-Glass & Steel like this disc. In my opinion it last 3 to 4 times longer than all the other brands I've used! In the photos that is the second side done with the same disc and it's still has grit to go !!! would definitely buy again, but what I purchased will probably see me to retirement. Thanks Steve
