Many of the headliners have kind of a hard cardboard backing. Do not crease it because it will not go away. This happened to me once when I removed a headliner from an Astro van to do a dented repair. Many headliners are really hard now.
Yup, I had a collision shop crease a headliner on a ‘14 Fusion re-installing it and the crease never went away. Average car on the road is a 2009 right now so yes, 04-05 cars that people are calling modern are old. I live in one of the hottest sunscorched cities in the US. People with 2 year old leased cars have roasted their clear coat and plastics. Yet I don’t think I’ve seen a modern car with a droopy headliner they don’t make em like they used to and thank god for that.Many of the headliners have kind of a hard cardboard backing.
