Youll know if clay is aggresive by the label on the box.LOL Seriously the clay is alot harder and usually not a over the counter clay.If you buy Meguiars,Mothers, Clay Magic they all say whether they are aggresive or not. Aggressive clay can actually marr the paint and in most cases scratch from improper use.
Glaze is a form of a polish but it really brings out the paint on a darker car like black.Glaze is breathable and can offer minimal protection.I would glaze fresh paint but not wax it due to new paint needing to cure. Detail products really are a science.There is no one size fits all Polish,wax,sealant.
Carnut on white I would recommend clay,#80,#7 and #21 sealant. I used this on my GT/CS and it always looked HOT!!! NXT is ok over the counter product.Its not going to floor you.

Look closely you will see a house reflecting in the drivers door.
