Sure! Have them, use them. They last a good amount of time and they do the job they're supposed to do. Since they're on the rough side, I use them for base coats, to resurface and as an undercoat for a higher grit (3000, 4000, 5000) and for polish,

They have 4 million uses around the house, garage, yard and garden. So I always have some on hand and scattered about.

I use them all Scotchbrites, Wet/Dry Sandpaper they all work fine and are cheap.

Yes, I still use them.  The gold gets the most use, followed by the gray.

They do hold up well, and like charlest, I'm usually using them to get to my base grit.

For those who have spinners, try adding some compound (such as Storm #2, or Brunswick Royal Compound)  directly to the Scotch Brite.  It's just another way to "fine tune" reaction somewhere between dull and shiny...

Agreed with Charlest. Love using them as a low grit then coming back with a 1000 or 2000 pad. It's money!!!!  Plus the everyday possibilites for use that come up lol

Anyone know in a general area what the grit equivalent would be?

3M Scotch-Brite Chart
Less Aggressive  -------->  More Aggressive
7445 7448 6448 7447 6444 7446 7440
Finer Finish     -------->  Coarser Finish

(The CAMI grit value is directly from 3M. The FEPA value inside the parentheses is the equivalent.)

7445 - White pad, called Light Duty Cleansing  - 1200-1500 grit CAMI (Talc)  (~2500 grit FEPA)
7448 - Light Grey, called Ultra Fine Hand      - 800 grit. CAMI (Silicon Carbide) (~1600 grit FEPA)
6448 - Green, called Light Duty Hand Pad   -     600 grit  CAMI (Silicon Carbide) (~1200 grit FEPA)
7447 - Maroon pad, called General Purpose Hand - 320 grit CAMI (Aluminum Oxide)   (~320 grit FEPA)
6444 - Brown pad,  called Extra Duty Hand      - 240 grit CAMI
7446 - Dark Grey pad, called Blending Pad        150 grit CAMI
7440 - Tan pad, called Heavy Duty Hand Pad     - 60 grit CAMI

Blue (pad/sponge combo) Scotch-Brite is considered to be about 1000 grit CAMI (~2000 grit FEPA).

I agree that the scotch-brite hold their grit level throughout the continued use of the pad, unlike Abralon.  The only negative I see with Scotch-brite is that when you get to the lower grit pads, they leave a considerable amount of sanding lines on the ball.  A new low grit Abralon pad seems to leave a bit smoother and more consistent surface, but you will never get the same grit again, even after one use.

i use them all the time. the grey ones eapecially that are at 1000. i prefer them over abralon or siaar pads and cheaper
