Here's how to remove scratches without going to the body shop:
1/ For scratches, apply acetone (nail polish remover for example) on a clean cloth then gently rub the scratched area until it disappears.
2/ Polishing with a polishing machine and polishing paste. Count about a hundred dollars for these products sold in specialized stores.
3/ Gently sand the bodywork then apply the polish.
4/ Make small circular movements.
5/ Leave the product on for a few hours and then clean with a clean cloth.

For deeper scratches, you can use a touch-up pen (between 20 and 40 dollars).
It allows to cover the scratch with a thin layer of paint.
1/ Lightly sand the surface.
2/ Shake the pen vigorously then apply carefully to the scratch.
3/ Leave to set for at least 2 hours.
4/ Cover the paint with a varnish.

Another even less expensive solution is the "scratch remover" products (about 15 dollars).
1/ Put a small amount of product on a cloth.
2/ Apply it on the scratch with circular movements.
3/ Wipe gently without rubbing.
4/ Repeat this operation until you get the desired result.

Finally, here is a natural method to camouflage a micro-scratch.
1/ Roll a damp cloth in cigarette ash and dab gently.
2/ Apply toothpaste to the micro-scratch with a damp cloth and polish lightly.
3/ Gently tap the micro-scratch with a dab of clay stone applied on a cloth around the finger.
