HI! I changed my tires yesterday and didn’t pay attention when lifting the car with the jack. Now I ran away the paint at the bottom left side. After that I smeared the spot with clear varnish. My question: Do I have to be afraid now that it starts to rust. Why is the paint down there a bit rougher than the other one from the car? Can one have such a small spot repaired with Smart Repair? Photos are included.
