Same with any grinding compound: The components are selected for their 
shape, hence 'cutting' ability, hardness, purpose, cost, etc. A compound 
with large particles with sharp edges will cut deeper and faster than 
one with particles of a softer and/or more rounded shape. The kit I 
bought came with a paste consisting of rhyolite and whatever semi-liquid 
was used to make it a paste; it appears aluminum oxide is also used.

A coarser compound will remove deeper scratches, but leave its own 
scratches. You can start with a coarser compound to remove larger 
scratches, then switch to a finer compound to remove smaller scratches, 
and so on; just like you might start rubbing paint--or filler--with 
320grit sandpaper, then 400, then 600, 1200, etc. Some polishing 
compounds do that 'automatically,' they start with larger particles 
which themselves break down to smaller particles and successively smooth 
the surface. McGuiars (sp?) has several compounds, all graded on a 
thermometer-like scale for their cutting (deep) or polishing (fine) 
characteristics.

I appears the lapidary (mineral-polishing) crowd has lots of discussion 
re: best compounds. Cerium oxide is mentioned a lot, rhyolite some, but 
I didn't see any mention of zinc oxide. Zinc is a soft metal and may not 
lend itself to being a good polishing compound, for glass anyway. Cost 
will (always) be an issue, rhyolite may be a better compound than cerium 
oxide but may cost more, or vice versa.

                              are some some places that polish
                              windshields. But ultimately it may be more
                              cost-effective to simply replace. Triplex
                              is the brand to use; an OEM manufacturer
                              that supplied them back then. The rest
                              often donâ??t fit right and eventually crack
                              from stress points, as Iâ??ve found. <br
