Does anyone make a reproduction of the black piece of trim that goes around the glass of the rear hatch? Mine is rusted and in need of replacement.

 

Not that I was ever able to find.
You'll likely have to do something similar to what I did.

I sanded it down, taped everything off really well, did two coats of rustoleum rust reformer, then did two coats with gloss black appliance epoxy spray paint(one of my favorite paints in a rattle can, but creates a TON of overspray so be careful if you use that).
Mine was pitted pretty bad, but even though it's not perfect it still made a huge difference.
