I'm working through my recently purchased 1979 and there's this black "coating" (almost looks like tar) all over the windshield wiper mechanism and cowl area. Is this original or something the previous owner did?
My 73 was even worse than yours. I made Dams on each end of the wiper trough with masking tape and then poured in Goo Gone liberally. Let it soak for an hour, then used my plastic flat bled trim to remove the hard as steel sealant. Let the Goo Gone do all the work. Even the nuts holding the wiper mounts were completely covered with the sh t.

Thanks for the suggestion! I really was not looking forward to scraping all that crap off the cowl.
The Go Gone made the stuff on soft, and I used a plastic trim tool remover to lift it out of the trough. If you let the Go Gone sit an hour or so, the stuff will be easy to remove. Once all the sh t was removed, I cleaned everything with 409 cleaner, then applied a coating of Mequiars Black Plastic Restorer (to lazy to paint). I never added any sealant because the car is never driven in the rain. Haven’t noticed any leaks when I wash the car.
Mine was pretty bad also. I used the goo gone in the spray can and a chisel edged putty knife. At times I used a mallet on the end of the putty knife at a shallow angle to chip away at it. When is was all cleaned out I used the same product in liquid form and soaked rags with it and wiped everything down repeatedly to dissolve any remaining tar product. It came out good but it was about 2 weeks of work. Definitely worth it in the end.
