Chipped paintwork on front arch

[Ben350]

Hello everyone,

 

I’ve just noticed on my front left wing there is a slight chip in the paintwork exposing some bare metal. No idea how this has happened, presumably a stone was flicked up by the wheel and it struck the arch right on the lip.

Is this something I need to get sorted soon and is there a risk of rust spreading throughout the arch? Can this just be touched up, or does this kind of thing mean the arch must be re-sprayed? 
 

Thanks.
 

 

For some reason, pictures posted from my phone like being sideways.
