I am looking for chemical makeup of "Valve Grinding Compound" or
"Course metal polish."  This material is typically used to seat valves
or polish metal.  Possibly, I am looking for a bulk supplier of a
Valve Grinding Compound that:

1.) Adheres well to surfaces to be treated
2.) Is water-soluble.  
3.) Must be easy to remove with just water and a brush.

Please send me the ingredients, grading and suppliers of this type of material.

I have located information on numerous valve grinding compounds. The
info includes manufacturer, composition, physical characteristics, and
solubility. I haven't found much info on grading. Perhaps if you
contact the manufacturer they will supply that data. Let me know if
you will accept what I have found as an answer.

This information sounds acceptable if it also contains the ingredients
and physical characteristics of the product.  Please make sure that
these are able to be purchased in bulk.

Thank you!

Hello felixtkat1,
     This was a pretty tough question, but I think I have found what
you require. Here is a list of the most common abrasives used in
lapping compounds:
Silicon Carbide
White Aluminum Oxide
Boron Carbide
Garnet
Diamond
These abrasives are used with various greases and water soluble
carriers in combination with different grit sizes to make all lapping
compounds. Following are links to MSDS spec sheets for several
manufacturer's compounds:

http://www.goodson.com/msds/VLC-4.pdf
http://msds.ogden.disa.mil/msds/owa/web_msds.display?imsdsnr=186107
http://www.wurth.com.au/msds/0890_199.htm
http://www.us-products.com/sitehtml/techdatamsds.html

These two links are for information about "Clover" brand compounds:

I could not find any pricing for bulk product for any of the brands
mentioned above. It seems that the manufacturers sell in 1# cans.
However, I found the following information on bulk silicon carbide. If
you want bulk quantities, you should be able to mix your own compound
using the provided information.

I believe that this should answer your questions and allow you to
accomplish whatever polishing/lapping you have in mind.

Good luck, Redhoss

Redhoss,

If you could help me out on the grit sizes that would be great!  There
will be a Tip in it for you.

Please let me know if you are interested.

Thanks!

Sure, I would be glad to help any way I can. Did you look at this link:
http://www.newmantools.com/clover.htm

It has a complete list of grit sizes compared to type of finish
required. If this is not what you need, let me know and I'll look some
more.

This a clear answer to 95% of the info I was looking for!  Great job!
