I thought Audi paint was supposed to be hard. I detailed member's (Autopia) A4 today and I can say with confidence that the paint was not hard. In fact, it was soft. The clay procedure induced more marring than normal (and there wasn't much rust), immediately contradicting the "hard Audi paint" notion. Confirming this was the fact that when I even PO85RD and an ultra soft propel via PC had a hard time finishing down without leaving noticable gashing, resulting in a slight haze; as a result, to have a proper finish I had finish down with the rotary which proved to be a tall task. Twas soft.
