Don't do it!!!
If she wants a pink moped I've got a maxi frame and fork I'll paint pink and trade you for the Pinto frame, all the parts will transfer over.
If you are going ruin it and paint it, please take it apart and do it right. 90% of how the bike will turn out is in your prep work; strip it down, sand it, clean it, prime it, paint it, polish it.
Attached is a pic of pink pinto, puke on wheels IMO.
