Panel replacement separates the men from the boys. I, unfortuneatly, am a member of the latter. But from my view from the bleachers the acid test is 3 levels of expertise: flat panel, simple curve, and the pizza resitance compound curve. Panels are available from AS for thier weight in gold, but can be made from aluminum sheets. The compound curve (bendy in 2 directions at once) needs someone with real know how and some specialized tools to fabricate.
