Swirl

If you look at your car under a bright light, for example sunlight, sometimes you may see very thing scratches in the paint. There can be lots of these, like someone’s draped multiple spider’s web across the paint. These tiny scratches are catching the light such that it masks the colour underneath and you don’t see it. This robs the paintwork of its true deep colour. The sharp edges of the Swirl mark are catching the sunlight and directing it up to your eye so you see sunlight along the Swirl mark, not the paint colour. This is why these bleminshes are particularly prevelant in bright lights – sunlight, halogen lights in petrol stations are kinds of light that really show up the marks!
