Laping Compound Grades

[Sterling Brundick]

I understand that there are at least 2 grades of laping compound (a/k/a valve grinding compound).  A course and a fine.  Can someone tell me what these grades are?  I thought I had a tube of each but it turns out they are both the same.  Neither tube actually states the grade.  They are both Permatex.  One tube is older than the other.
