Gary,

CEO can range in sizes depending upon the grade.

For example MicroAbrasives has 5 grades CEO#1 - CEO#5 ;)

They have Particle sizes ranging from 1-8 microns to 1-12 microns with the
average between 1.5 microns to 3 microns, and while I am at it they also
have a pH between 6.0 and 8.5

With CEO size isn't everything, the polishing is also a chemical process.

Is it interesting that this topic came up because I was talking to my
supplier about CEO just today.

I have been using MicroAbrasive CEO#3 for years for GotGrit.com and he was
suggesting I try the 1660. (Many of you know Randy)

I am considering ordering a sample and try it out.

The one thing that will be hard to visualize is the 1660 is WHITE, wierd I
am so used to CEO being brown.

Anyone else already tried the 1660? And thoughts on it vs Micro CEO?
