buffer paint

friends, I have a question in the parts of the vehicle that I marked in the pictures, there is a matte paint from the previous owner, but there are peels, which creates a bad image. If I completely disassemble the paint, what would you suggest in the scratches under it, how can I paint it here? or do you have any other suggestions? & nbsp;

Dude, you need to repaint him to a good painter, but first there are primers for the plastic floor.
