Started pulling the old fuel line, and, as I worked my way forward, realized the whole underside is coated in a dry tar-like material. This 1963 dealer rustproofing, a 70s JC Whitney thing, or what?
Any way to get it at least mostly off without blowing the car apart? I fear it'd turn into another unfinished project if I did that.
I have been doing these cars for years that tar like coating you refer to is factory undercoating/sound deadner propane torch and a scraper warm it a little and scrape it off
