mate pick a different colour, the nighthawk black although looks good for about a day if detailed by a pro, after that as soon as the sun warms up the paint it seems to flex/expand/etc and the swirls eventually come back, sometimes worse than before.

If you want swirls go balck, no matter what you do you will always have them apart from that day or so after being pro detailed (by pro don't mean your average car wash)
