For Koch Chemie Green Star you need the Alkaline version because it is an Alkaline product so the blue variant. The black variant is for acid resistant. In this video I use the acid variant, it doesn't really matter as long as you rinse them well with warm water after each use.
Great work! Which version of Marolex do I need for using Green Star and Protector Wax? The industrial version ?

TRC blue clay is not aggressive enough IMO.
