To Powder Coat or Not

I'm thinking of letting Leanna do her magic and powder coat my '70 Duster grille and headlamp bezels. Not sure if I want just the original painted surfaces done and leave the edges bright or to blacken entirely. Thoughts?

I meant to say the grille mouldings, headlamp bezels and turn signal bezels. Just the aluminum parts as paint chips easily from them. The plastic parts painted. I will check with her before of course. Just wanted to know if anyone has done it, if they like it and some opinions.
