Should I just go ahead with a full repaint?

There's a few different types of trim removal tools, haven't taken any trim off a Duster before but have for a few other cars. This is the tool I use, you slide it under the trim until you get to a clip and then with a little pull the clip turns and releases. This is assuming the clip is rectangular and as I mentioned I don't know what type of clips the Duster uses so you'll need someone to chime in.
