Looking for DIY trim restore tricks

Hello FABO!

I am getting to the point of installing trim/grills. (1967 barracuda) The trim isnt horrible but not up to spec to the rest of the car, so Im looking for the tricks to get dents out and polish or to replace those studs in the grills? I thought I would make a mold out of JB weld or something in the spots that were nice and use them to tap the dents out for the rear upper and lower decklid trim. Not sure about the grills where they meet on the outer edges. Ill post some pictures of my dilemmas tonight.

Any thoguhts/secrets?

Thanks FABO!
