Can you let me know what product you tried? This one is a whitish paste with a pleasant smell which I apply on clean cloth and rub on the affected area. I think (hope) the light scratches (i.e. paint marks) are gone for good. But the deep ones cannot be removed and are only slightly faded. Hope they don't resurface.
Where paint itself is damaged, nothing can be done except to repaint, which will cost a lot more.

Painting is the permanent fix.
