The headliner in my 1987 Thunderbird is starting to tear up, and I want to put in a big american flag in its place. The headliner seems to be a board with foam on it then a soft light material on top of that. I did a search and found out that 3M Super Trim Adhesive #08090 is good, but is stong enough to hold up a flag? I think the flag is heavier than regular headliner material, and made of different material. I've never done any work with headliners before, but I want to do this myself and I don't want to take it to a pro.
here are some pictures of my headliner as it is now:
