Best way to touch up chipped gesso

[CalicoFraming]

Hi all

I've got a moulding with, so I'm told, a gesso coating underneath the gold finish. The mitres are a little ragged through the gesso and there is a tiny chip in the bottom outer corner of each mitre - can anyone give me some tips on the best way to make good this damage?

Thanks as always
Calico

Liberon Gilt cream. You will need to get the right shade though.
