ERA,
The material is 1.5 millimeters or about 0.060"
I do not know exactly how much material is removed. I would imagine 10-20% during a full polish job.
The polishing does not make the material brittle. The skin will work harden, like any metal, if it is cold-worked. Our bodies work harden when we make them.
I have no idea how much weight is added to a car when it is painted.
