Got a lot of stonechips on my bonnet, getting repaired after xmas, would I be ok to use some nail lacquer to protect the exposed metal in the meantime?

yeah that would be fine, to be honest get some correct paint code and a toothpick and touch up the paint first if you have any rust use and abrasive pencil.  stone chips are quite easy to touch up and make them look decent.
