Bought a C4 last year and according to salesman the paintwork was perfect. I hadnt seen the car and it was washed when I went to pick it up. After I washed it myself, I noticed that there were a lot of minute swirls from previous owner and perhaps myself. Decided, to get Ally to them! Ally has some before shots but here's a couple of after shots.
Now I just have to make sure I wash it correctly to stop the swirl marks re-appearing.
Cue for Ally for product recommendations...
