The Saturn got a lot of flack from “journalist experts” for “large panel gaps”
Those were needed because the frp material has a much larger coefficient of expansion with temp.

But I suspect the real challenge to selling aftermarket frp replacements is price. Not many folks would spend 3 or 4 times the price of a replacement Chinese sourced sheetmetal part.

How about some Photos or engine or MPG SPECS?

Wonder if I could resurrect that tech in the aftermarket here and now?

Probably not.

I believe that most aftermarket body panels are made using old dies purchased from the OME.

FRP would use molds. The molds would, I think have to be made from scratch which I think would drastically increase the price.
