The reason chemical companies do not label their compounds by grit size is that they want the detailer to believe their products are "special."
There is a fear in the chemical business that detailers will discover that chemicals are really nothing but a commodity. That is, you compare apples to apples and you have the same thing. Just like lumber; grass seed; sugar, etc.
The reason we do it is because we believe it to be the easiest way for detailers to understand the differences between compounds, just like sandpaper.
Even at that there are differences in compounds. Some work fast, using less oil and a mineral spirits fast dry solvent. Others, like ours, for example, have work longer to prevent damage to the finish as they have more oil and use a slower drying solvent.
It really takes work to determine what is the best product to use.
The Comparison Test of Waxes and Sealants is probably one of the first objective comparisons you can use to see how the wax or sealant you might be using matches up against others. One of Meguiar's products was last on the reflective gloss list.
