So I am going to deaden my doors before my new comps get here. I take the door pannels off both doors. On the passenger door everything looks good, installing will be a breeze. On the driver door, I had some work done about 6 months ago. The plastic sheet that covers the door skin has black goo on it. So thick that when I try to take it off it streches like pizza cheese, stickes to everything and wont come off. Now I have tried everything that I can think of to get it off. Does anyone have any ideas? I have tried, rubbing alcohol, soap and water, spatula to scratch it off. Nothing works, all I have now is this huge mess of black goo.
The only thing I can think to do is cut the plastic around the goo and deaden over it. But that is my last resort.
EDIT: If I get home before dark I will post some Pics. Pics at bottom,
