First, let me state that I'm not a big fan of scales. Why? Because they can become somewhat subjective based on level of experience. Take salsa for example. They have these scales on the bottle that show the heat level. Well, I know someone who thinks that "mild" is blazing hot while some folks might think that the "very hot" is more like "medium" (Personally, I'm used to habanero sp?

).
Many of you have noticed that our products stay 'wet' longer. This allows for a more controlled type of cutting. We've had to show some shops that instead of running high rpms on their rotaries, which can cause the product to 'gum' up and not cut well, they need to run it slower (about 700-1000 rpms) than they are accustomed to. Without such knowledge someone who is not working the product for a sufficient amount of time or running their machine too high for the product to do its work properly might consider the polish to be a 6 cutting level instead of a 8/9.
Here's a general guideline:
D2 Special Cleaner* - ~11 - Not available in N.America
Extra, Intensiv Paste* - 8/9
Paint Polish, Hochglanz Polish* - 5/6
Metallic, Express, WaxFinish* - 2
WaxPolish Soft -1/2
*Glaze: silicone-free for professional environments
As a general guideline, I hope this helps. Level of cutting can be changed dramatically by the pad you use, the application method, the rpm used, etc. Something to keep in mind.
