I tried doing a search and couldnt find any answers.

Does anyone know what each color scuff pads equilevant grit size is?

white?
maroon?
green?
gray?


Im asking only cuz Ive seen ppl highly recommend their use for prep work before spraying bc and/or cc.

TIA!

Recently I had a discussion with a 3M rep on their tech line. This is the information he gave me, note that this will apply only to 3M products, though I believe other companies copy the color code somewhat:

white: p2500
maroon: p400
green: don't know, have never used green, so didn't ask.
gray: p1000

Also, the white pads have soap in them for use with water.

I use the maroon 3m pads daily... seems like 320 - 400 grit to me. Put it on a machine buffer and it cuts more like 220.

I didn't even know they had a finer grade than the marroon ( grey) until reading here a couple days ago.

Maroon - 320-400 grit
Grey - 800-1000 grit

I use Scotch-Brite pads to resurface proactive bowling balls. The pads will wear down the urethane surface without breaking the mica particles impregnated in the urethane to produce bite on oily lanes.

SCOTCHBRITE GRIT CHART

7445 - White pad, called Light Duty Cleansing - (1000)

7448 - Light Grey, called Ultra Fine Hand - (600-800)

6448 - Green, called Light Duty Hand Pad - (600)

7447 - Maroon pad, called General Purpose Hand - (320-400)

6444 - Brown pad, called Extra Duty Hand - (280-320)

7446 - Dark Grey pad, called Blending Pad (180-220)

7440 - Tan pad, called Heavy Duty Hand Pad - (120-150)

Now that's wierd as all hell, around here the green are coarser than maroon. I thought they were scotchbrite but maybe not.

green are the coarsest I thought too. I've never seen anyone who uses them?

Yeah, the green around here are darn coarse. We use them with liquid strippers in our furniture restoration shop for stripping touch-up.
