i need some help on removing targa top trim peices that screw on both lefta nd right sides of the targa. it is held onto the targa with a black silicone/goo that is very sticky and does not come off easily at all. i ruined both of my origional trim peices removing them. i was wondering what kind of agent can eat this goo off so the trim falls right off. i have tried finger nail polish remover and gas to no luck. any help would be appreciated. thanks
