[QUOTE=001mustang]I've used 2200 before and could not tell difference compared to 1600 after 3m 5973 compound then polish. I just compared w/ my untrained naked eye.

No down side to working up to 3000 other than time and money.[/QUOT

You can buff out 1500 grit scratches the only difference it that it takes a lot more work when you finish with 3000 a light cut is all thats needed

How can you tell when 3000 has cut to the bottom of 2000 grit scratches?

Well after you are finished with the 3000 Trizact you will have a shine you can see if there are any scratches left behind and then its very easy to buff the rest out

Maybe Santa will bring me a bag of 3000 grit.

I dont know if you have ever used this or not but it is not a wet sanding system you use a DA and a interface pad

Is it tricky to use that 3000 grit system on convex, concave and other difficult surfaces?

The soft interface pad works great on curves. Still be a bit careful on edges, it doesn't remove much material but if you're a little thin sowmwhere, it'll probably manage to make it gone instead of thin.
