Great work man. I've been following your thread since its beginnings.
With my HIC project, I had trouble getting the Bondo smooth, and there are slight irregularities in the surface of the Bondo on the frame. Looking back, I wish I would have done it a little differently, but it still turned out pretty good. I actually like the irregular look to the frame, it looks more like the irregular carbonite on the front.
What was your technique on the seam between the frame and the rubber? I've got to go back and redo this part when I install the side panels.
