Cleaning / restoring black plastic below windshield

[Jamesp]

The repair worked very well. the corners are slightly raised due to the additional material (epoxy and glass fibers) under the plastic cowl where it bolts down, but unless you know it is there (i do) it is not noticeable. I performed this repair with the plastic panel off the car, and made sure to have a thin layer of glass reinforced epoxy (5 minute epoxy) on the top and bottom of the broken piece. The hardest part was figuring out how the broken end pieces under the nuts fit onto the cowl after everything was removed, so pay attention to the geometry when you take it apart. Not a hard repair but getting the epoxy/glass into thin layers so everything fits back together is fussy.
