I was reading Red Rocket's Satellite restoration site and he faced the same thing, a roofing tar-like substance in the trunk. He had it in the trunk extensions and I'm having a hell of a time getting that crap out of the left extension.
Is this common practice? If so, is there anything besides mineral spirits that'll get that crap out of there? I'm so close to primering and painting the interior, but I'm not gonna until that tarpit of a trunk is completely spotless.
God I hate the previous owners of my car right now. . .

Okay, I feel much better now. ..
