Re-paint brake calipers - suggestions and recommendations?

[ei99]

I need to re-paint my front brake calipers (which are stock red ones on a Golf GTI Mk6) because they're pretty scuffed and have a few chips

Does anyone have an opinion as to whether to re-paint without removing them (ie. masking etc to avoid overspray) and removing them entirely to re-paint? Have been told that second option is better (but probably more expensive).

And is there anyone you would recommend to do this in Perth?

Thanks for your suggestions/recommendations
