Hello ali. I had the same problem with my mercedes. 2 small paint chips on the hood. Not visible if you wernt looking for them but it made me cringe everytime i looked at them.
Anyways, a member on a benz forum helped me get a mercedes touch up paint restoration kit after i gave him the VIN and color code of my car. However there are a few brands that make these kits and they work perfect. I'll pm you the pictures but this is what it looks like.
You may have to fill in the hole of the depth is too much. mine were surface chips so a few layers + clearcoat did the job.
