Stone chip on roof - Advice needed

[Freemo]

Hi All

I have a Belle ile Blue with a black roof.

Yesterday whilst cleaning I notice that I have a small paint chip in the roof on the drivers side. the black paint has come away and revealed the Blue below. Is it about a millimeter in diameter.

Whats the best way to get this fixed. Although you can not notice it much i know it is there and it is really bothering me.
