As per the title really. They've run a key along the driver/rear off side door and also along the front wing. On the doors it's not gone through to the metal as far as I can see, but they've really ****ed up my wing and it's definitely in need of urgent attention to prevent corrosion.
What's the best thing to do in the short term to prevent this, for the next few days, until I can get to the scrappy to get a new wing (not paying to respray, the car is almost worthless)? Would vaseline stop the air/moisture getting to it? What about WD40 or waterproof grease?
Pictures:
Thoroughly ****** off about this
What mindless actions

I think I'd actually flip my lid if that happened to my M3
