to repaint or replace or to not

Im upgrading my bike and my latest mod is shimano ef41 3x6 and a pair of locking handles. As this is a bike i got for free the stem and handles have some surface rust on them and i have 2 options. I can get an anodized or whatever handlebar, run some sandpaper and respray the existing one or keep it looking a bit "ugly" as a theft detterant
