The ’79-’93 Mustangs had this weird beltline trim that ran all the way around the car, along with the cool ‘louvered’ trim pieces behind the quarter windows. My ’82 GL came with some chrome pieces around the windows that made the car look like a grandma’s car, so I blacked ’em out to look a bit sportier.
I still have some spots to clean up and tweak a little with the Sharpie, thanks to the Testors masking tape lifting up in a few places. But all-in-all, I think masking and airbrushing the black trim came out pretty good.
