Bloody scratches on my nice black paint in the form of light swirl marks. I knew that black would be difficult but didn't realise just how sensitive the paintwork is. Gave it a really good clean today and the marks are visible in the sun. Pain in my ****. Hasn't even been out of the showroom for a month!! What do you use on your black A3s? Is that Turtle Wax Scratch and Swirl remover any good? Opinions please and advice.
