If you use P-graded sandpaper it's the same. When you use U.S. graded paper then it's like this:
P1000-550 ANSI/CAMI
P2000-1100
P4000-1500
When I say the same, I mean in depth of the scratches. Abralon leaves a much rounder scratch and because of that the finish is noticeable different. You will get a smoother finish and ball reaction. P1500 grit sandpaper for example, gives a much coarser/rougher result then P1000 Abralon, which also leaves it more glossy.
In my opinion Abralon has a more even sanding pattern. When I sand with paper, sometimes some lines are deeper then the rest. These lines are hard to sand out with the next grit level.
greetings,
Antoine

also be careful some wet dry is imperial grade witch is similar to abraons numbering system

I always thought
2000 grit Abralon was closer to 1000 grit CAMI (US)
and
4000 grit Abralon was closer to 2000 grit CAMI (US)
1000 grit abralon was in the 550 grit CAMI range (500 - 600)

road94master, I assume 600 grit green pad is an OK approximation to 1000 grit Abralon.

What perplexes me is why can't there be a universal system for grits? I know there are different uses for them across the board other than bowling balls (wood, auto, etc) but why do these bowling companies keep it so hush hush of what abralon and the like? Up until I started lurking on this site, I thought 4000 abralon was a 4000 grit finish. Come to find out, it is actually 2000 grit. Why did the companies feel the need not to disclose this information?
Reminds me when Track had all these different unknown coverstocks with no reference to what the out of box finish was.
Very frustrating practice if you ask me.
Okay, rant off.
No problem. I understand, Believe me, I DO!
But as far as I have been lead to understand, all abrasive manufacturers here in the US will be going to the FEPA standards, mostly because they are more precise and the resultant abrasives are more consistent in their overall ability to change a surface from one level to the next. I hesitate to use the word "smoother" because that implies something else. I am not sure howm uch longer that will take. Many sandpapers already have the "P" preceding the number.
I believe only Scotch Brite still references CAMI numbers. However, I doubt they'll be changing their nylon pad manufacturing process. Maybe just the numbers will soon be FEPA numbers rather than CAMI numbers.

Thanks charlest.
I have learned quickly to peruse your threads for technical information. Thank you and keep up the good work. I for one appreciate your knowledge...and candor at times!
Thanks.
No, I won't win any popularity contest, will I? And so it goes.

Actually 3m, which owns scoth brite, is in the process of swicthing over our converstions and to the FEPA system(red sand paper). I took a sample home and it's alot better cut too!

This is going to change everything when i am doing surface adjustments. I want to get ahold of some 2000 US sandpaper, but have not seen any of that yet.

well I am glad I am hearing this lately. I was always thinking 4000 abralon was atleast 3000 in regular US standards. With it being only 1500 that, no wonder I was getting so much burnup with my Uprising last week. Looks like I am going to have to keep it really polsihed.
That chart, as far as 400 grit Abralon grading goes, goes against everything else I have seen. As far as I know, 4000 grit Abralon = 2000 grit US/CAMI.

so anything with p in front is that same as abralon?? fepa grade right..
AS far as I know, yes.
Normally, FEPA graded abrasives have the "P" before the number. CAMI (US) use only the number. We recently learned that Abralon, designed and manufactured in Europe by Mirka, does not use the "P" but is graded using the FEPA system.

By the way, when you buy online, it's alwasy safest to double check. Sometimes the box is marked "P1200" while the paper itself says, "1200". With American manufacturers converting to the FEPA system, some may just assume everyone knows what their paper is. DO NOT ASSSUME.

The bad thing is I cant fing anything ove 500 grit wet dry sandpaper around here. I went to lowes, home depot, gill roys..
I think that's because most finer grades are used either by auto body shops, boat shops, or by professional places surfacing things like Corian.
So most finer grades can only be bought online. PLUS since they are such high volume businesses, they are getting the newest runs which are most often graded using the FEPA standards. That is they have a "P" preceding the numbers.
Easy to translate to US grade, any thing from P1000 and up, just divide by 2.
P1500 = 750 US grit, P2000 = 1000, P2500 = 1250 US grit.
See http://www.woodworkingshop.com/cgi-bin/097F0268/mac/qryitems.mac/itemDisplay?qryType=STYLE&itemSt=SH91100SC&coreDsc=9%22%20X%2011%22%20SILICON%20CARBIDE%20SHEETS%205PK
At the bottom are 1500 and 2000 grit. Pretty sure they "P"/FEPA graded.
Supergrit.com:

At the bottom are AZGUY's Rhynowet Redline Sheets. They are "P"/FEPA graded.
Here is Supergrit's P2500 grit wet/dry silicon carbide sheets:

There are more places like these. Just do some internet searches.
