I should have mentioned that I'd picked up and tried Meguiar's Ultimate Black plastic restorer and wasn't all that impressed.

I tried it on the side glass forward plastic triangles and it helped, but wasn't what I'd call an ultimate black. I did two coats as suggested.

Perhaps I'm putting too much stock in the photo I saw, but that engine bay's black plastic was definitely an ultimate black.

Several others all agreed that whatever the brand was, it was hands down the best.

While I doubt it, the owner might have actually used SEM plastic paint which I use a lot when restoring older Alfa's. I prefer to keep the plastic un-painted but be able to get that really deep black.

I'll check into Zaino wax.
