Always looking for the better mousetrap, I gave it a try. While it does leave a shine, Gunnert's advice is correct. It is not a cleaner.
We are on well water at the house, and my nemesis is water spots. The Motul product has no effect on them. I did a side-by-side comparison on painted surfaces and glass with Motul, Honda Pro Cleaner, and Lemon Pledge.
Only the Motul spray would not remove the water spots.
It's fine if you start with a clean surface. Very little effort required for a shine.
