I ummm put a scratch on my car door. It's down on the bottom so people walking by can't notice it. You would have to squat down to see it. But it's a long scratch. I am afraid that it peels the paint, and might lead to rust if left the way it is. (I am new to the whole car world). Is there anything I can do to seal it so it doesn't peel? I don't want the whole door painted for that small scratch.
