We have polishes and compounds from Autostolz Made in Germany, and Chemical Guys Made in USA.  Both are great products. 

Chemical Guys approach is more around particle sizes of multiple step polishing, you have larger particles to remove more paint, and go over with finer particles to remove the marks from the first step until you get to a final polish. 

Autostolz is a new Polishing manufacturer with a different approach.  All their polishes have tiny particle sizes, cut is instead achieved by making particles harder, and the chemical formulas of the polishing liquids.

Both are great brand and products, and it is great to be able to offer the range and give choice.

Here are two videos explaining the different polishing ranges of Autostolz and Chemical Guys, followed by a chart categorizing the range of polishes of both together.
