Small nick in finish, way to touch it up or keep it solid?

[devilfish]

Hi,

i refinished a strat body as part of a project using proper nitro lacquer, everything turned out very well.

I just realized theres a small 'finger nail' type dig in it on an edge thats visible and you can see a bit of the dark wood underneath the vintage white finish.

I know that **** happens and its just a shame because it isn't even finished yet. was just wondering how the best way to try and touch this up would be?

or to at least prevent further chipping in that area?

Thanks
