Damn. I don't have a basement and it's raining outside.
Guess I'll have to leave mine sagging...

Actually, I have done GM headliners (older Cameros and Firebirds and a few pickup trucks) by just spraying them with texture coat like the bedliner spray or trunk paint... only you thin it out a little so it is smoother. You can get any color you want, and NEVER have to worry about it sagging again. I'll post photos when I get mine done...
Or...you can take it out and leave it out, looks more like a race car that way...
JMHO.
