The Bricklin world has a major problem keeping the "skins" from separating from the metal. My unit had separation at the doors, had been repaired with silicone, not the right stuff, had come apart big time...silicone stuck to one side but not the other. Biggest problem was getting the old silicone off (used a narrow rotary wire brush on a drill motor). Consensus adhesive is black urethane used by glass shops to install windshields, take a lesson from the Brick folks. Les.

It is perfectly in place between the doors, and the doors don't rub the edges etc (I use a textmarker when I take the T-panel off) > > Still, after a day or two of driving, the T-panel "bounces upwards" like a bridge. Then I let the car stands still for a few days and did the procedure again. The T-panel still pops up in the middle. I can put my hand on top of the T-panel and press it down about a cm.
