I talked with NoD~ about his plans to convert his Neon to a hatchback and suggested that he strengthened the back for crash protection, but he is not planning a boattail--yet. Since your boattail completely absorbed the damage then your construction proved itself. It is aluminum skin over aluminum bar? Somehow I thought that a foam tail would work perfectly, since bumpers are made of that anyway, while a metal frame would bend the attachment points, but that was forgetting about the internal structure, and obviously, I am mistaken.

I would suggest welding in one tube on each side for rigidity but again, this seems to be irrelevant.

"Kiss the dog, kicked the wife," that was funny right there. Wrong, and I'll probably suffer for laughing at it...but funny.
Did you quote it to your wife?

My kids love the undieing POS project but hate to be picked up from school in it. So I think I will end here on that point.
Bright yellow green or orange suggested solid white if you dont run A/C.
Why did you paint the tail a different color?

I absolutely understand planning modifications according to ROI, but "aesthetics" seems far more important than economics to most people. I would be willing to pay more and undermine my investment, if it increased the chance of other people following my example, and hopefully figuring out a better way of doing it.
