You can also just use chrome vinyl and wrap them, it's really not that hard and if done right it will look awesome and last a long time. From my experience and research it's almost impossible to get a real mirror chrome finish from rattle can chrome paints. The vinyl looks like the real deal and is removable so if someone wanted to change the color of it, it's as simple as removing the vinyl.
