Help, my son has a 2004 Mazda RX-8 and the whole headliner material behind the sunroof is sagging. We just noticed this the other day. Has anyone experienced this and know how to fix?? I know its just going to get worse over time, so I want to fix it soon. Any suggestions or thoughts would be greatly appreciated. I check the tech forums and didn't find anything.

Thanks ....Rocket

 

I think your the first victim. PICS? Is it just the material separating from the backing? Or is the whole thing falling down? If it's just the material then find an upholstery shop and inquire as to what they recommend. Like gluing it back down. Has to be a very light glue so as to not saturate the material and show through.
