The very first thing I do with any car build is to find the chrome sprue and sink it in a bleach bath to strip all the chrome off. Every piece. Then I use ALCLAD to re-coat it.
"Model chrome" is far too shiny for scale realism. And really, you can't hide the detachment points. The only way to get a uniform finish is to paint it all. ALCLAD is not as shiny, but shiny enough in a proper "scale" way. Inevitably, you will notice the difference in shine between a painted and a plated part.
