solving interior problems my way:

• 1) I always hated sunroofs, so when mine leaked water, I cleared the drains, lubed the mechanism (tested fine), pulled the fuse, sealed the glass with PPF, and called it done. I never used it, so no matter.
  
  
• 2) Though I've never driven my '04 Chevy 2500HD with the windows down, it sits facing the sun without shade, everyday, forever, and the leading edge of the headliner had let go a couple of years back, anyway, so I used Gorilla Tape, then aluminum duct tape to hold it in place. Neither can work in the heat.Last time I used 3M Spray Adhesive (Super 77?) on another car's headliner, I created so many wrinkles, that I tore it out and spray painted the cardboard/composite backer with Krylon (it was on my wife's old '85 chrysler LeBaron Coupe, so it was no big deal).
  
  
• 3) So, this time around, I'll be trying a different method (before I resort to the paint method); I'll be trying these two items from Amazon (after the weather cools, of course):
  
  • a) https://www.amazon.com/dp/B0B49NYD3C...sin_title&th=1 "60PCS Car Roof Headliner Repair Kit, Auto Roof Snap Rivets Retainer for Interior Ceiling" and
    
    
  • b) https://www.amazon.com/dp/B0DLB591GH...d_asin_title_2 "Car Headliner Adhesive, Upholstery Glue for Cars, High Viscosity, Yellow, Waterproof, Heat Resistant, Automotive Adhesive" brush-on.

It doesn't have to look good, just stay up and not hanging down. The snap rivets will hold the bulk of the fabric's weight screwd"gently" into the backer, and the adhesive will tack up the frayed front edges (from the use of the ineffective tape jobs). why not try something different?
