68 barracuda trim removal

I assume you are using the correct trim removal tool and are very carefully locating the position of the trim clips around the edge of the windscreen before you are exerting pressure, at those locations, with the tool. As I understand, the proper trim removal tool has 2 arms that locate at either side of the clip, so you get consistent and direct pressure at these points and the trim should just pop off the clip. If you dont pry the trim off at the clips you will basically just be bending the trim. The trim should come off fairly readily if done this way - I managed to get my windscreen trim off without damage using a breadknife but of course Im not recommending that method (I just didnt have access to the proper tool).

Drip rail trim should be easy to remove. You could even slide it off the drip rail rearwards (taking care not to scratch the paint in the process).

Hope this helps.
