Thanks for the info.

Bricky,

Don't feel bad. What you did was excellent. Here's what I saved in my files when this subject was discussed in the recent past:

3M Scotch Brite:

7445 - White pad, called Light Duty Cleansing  - 1200-1500 grit
7448 - Light Grey, called Ultra Fine Hand      - 1000 grit.
7447 - Maroon pad, called General Purpose Hand - 320 grit
6444 - Brown pad,  called Extra Duty Hand      - 240 grit
7446 - Dark Grey pad, called Blending Pad      -  150 grit
Green Scotch Brite is available EVERYWHERE. It's 600 grit.

The Blue pad is a recent discovery. I've found it on pot scrubbers, saying it will not scratch teflon and non-stick finishes. So 800 is a good guess for its grit level.

When you resurface, pay attention to the particle type and ball type when choosing a method for resurface.  For example, you need sandpaper or Trizact pads with glass and ceramic particle balls, which silica particle balls should be resurfaced using scotchbrite -- not sandpaper.  For the most part, reactive balls work well with either, though I prefer sandpaper for finishing before a polish.

"It's just a carry contest."  

Mo Pinel put the scotch brite grits in a Bowling Thing Month Magazine about 9 months ago, here is what he had to say.

white=1500
light grey=800
green=600
burgandy=400


goodluck
