I have a pair of Grand Prix tailights, and I'd like to separate the red lens from the back part of the taillight housings where the bulbs are located. It looks like the lens is glued to the housing. A friend said that if I stick the whole assembly in an oven for about 10 minutes at a low heat (150 degrees F), the heat should loosen the glue, and I can separate the lens from the housing. It sounds reasonable to me, but I'd like to avoid any damage to the lens. Has anyone here ever tried this, or have any other ideas on how to do this? Thanks in advance.
