if you want it done properly the areas will be sanded down, primed and then you will have colour to these the red lines ive drew on, then the entire door and rear quarter will be painted (not the bottoms though below side strips).
quarter has to be painted for the metallic colour match.
you can goto one of those guys that comes round to have it all bodged in.. sorry, blew in for £70 or something if that fits your budget better. Just dont wash that area with a jetwash or breath on it as the paint will flake off.
3rd option is to just touch the dings in with some touch up paint.
