Is there any danger in using valve grinding compound to lap scope rings?
800 grit?
I am out of the stuff sold for lapping rings.
Thanks

Go to the auto parts store and get some valve lapping compound. 800X? you don't have enough life left to lap them with the 800X
180-240 You are not polishing them.
Thank you.
Ok, maybe this should be on the humor forum.
I go into the local chain auto parts store and ask the nice young man behind the counter if they had any valve grinding compound. He starts typing away and asks what make, model and year of car I had. I started laughing so hard I almost fell over. Made me feel bad, but could not help myself.
I had walked the isles looking for little green cans of Glover compound, but never found any. What they had was a tube of Permatex valve grinding compound. Nowhere on the packaging or tube does it call out the grit. I bought it anyway and have retreated to my cave.
Just found out this little tube has 122, 150, 180 and 220 all in the same tube!

brownells sells small plastic jars in various grits
If you're bedding the rings after lapping, the Permatex valve grinding compound gives an excellent finish for the bedding compound.
Good shootin' -Al
