Can anyone give me a rough cross between grit value to roloc/scotchbright pad color? Experience/trial and error will be greatly appreciated.

I'm about to start polishing the stainless steel exhaust headers for my ATV build and have been trying to get a grip on the color to grit relationship for a while now. Enco's site is the best I've come across so far. At least they include the type of abrasive. 3M's own site for the roloc/scotchbright media combination I found difficult to wade through and nothing regarding a grit comparison.

Brown - Course [grit?] Enco & Roark
Maroon - Med [grit?] Enco & Roark
Blue - Fine [grit?] Roark
Green - "Very" Fine [480?] Enco
Grey - "Super" fine [grit?] Enco

From a little trial and error of my own on an aluminum part, I think the green is something like a 480 grit? Prior to this, I didn't even know there was a "grey".

Since I'll be sanding all the way down to 1500 grit before I begin with the polishing wheels, it'll be really helpful and time saving to know, even roughly (no pun what the relative grit comparison might be.

Thanks

While trying to answer some of this myself, here's what 3M's web site says:

Course; Brown
Medium; Maroon
Fine; Blue? Nothing - apparently doesn't exist
Very Fine; Green
Super Fine; Grey

It's a whole lot of nothing and you should note: these are all 2 in. "Hook and Loop" not roloc. Trying to cut and paste their own description "Surface Conditioning Discs" into their search box returns ZERO results. Very frustrating

I couldn't get HF to tell me what the comparative fineness of the stick polishes were. Different colors, but what do they mean?
