I looked at your photos you linked to. I'm not blaming you for all that paint damage, but your photo shows your car on a gravel surface and yet you posted "I haven't driven in any gravel". Which I find confusing.
Your paint damage certainly does seem unusual. The only solution I see is to repaint the entire door and then put film over it.
So my question is, are there any ultrasonic sensors in the X front doors and will covering them with a film interfere with their operation?
The gravel is in my driveway. It is only a 30' long and... since it is a very narrow driveway (with cats frequently blocking they way!!) I drive very, very slowly. There is really no chance that the chips came from my driveway.
