Restore white painting on Nauticam housing

Does anybody have any experience to restore white painting on Nauticam housing? Any advices are welcome.

Thank you,

Never mind. Auto touch-up pen did a great job.

Thanks Vitaly,

I tried looking for an auto touch-up pen but the white pens at my local auto store (Super Cheap in Australia) had a national recall. I have been told that model hobbyist paint (enamel) works so I'll try that solution.

Cheers,

A good "Stay-At-Home" task that's on the back burner list.

I have used Testors enamel. It is a model/hobby paint in small vials. Use a small brush to apply the enamel. Since the lettering is inset on some housings you can use a alcohol wipe to gently remove the excess. 

I used the felt tip paint pen I write on my fins with, then lightly wiped excess with a paper towel.  Lasted a couple of months, but I need to retouch.
