On Saturday I was following my wife into town. I could see the sun reflecting off the red A3. I could not believe I could see halos from the swirl marks from about 20 yards away. Especially as I had detailed the car just a few weeks ago.I hate to tell you but red is a high maintenance colour for swirls etc.
I'm going to SRP and wax the rear of the car again. Then I'm going to stand back 20 yards and check it. If it removes the halos then I know it was the wash that Audi gave the car last week that did this.
