Vintage Karting Forum

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.

Sterling do a search for clover compound.

Most helpful.  Thank you both.
