Somewhere during modeling something I did something that I am unable to find how to fix. When active selecting my car mesh in object mode I get this strange orange edge stripe, that I cannot account for. In edit mode I tried already selecting the edge and clear sharp and clear seam. Also mesh cleanup -> merge by distance but there seems only one edge. Because the mirror modifier the orange line appears also on the other side ;-)
What could cause this effect? And more important, how to get rid of this line that doesn't fit the outline of the car.
