Happy Headliner Glue Day!
It was not as warm as I would like it, but it's not going to improve, so we went for it today. Always nice to have an extra set of hands, even if those hands are 8 and 9 Years old.
If you did not already, put all the grab handle bolts, seat belt bolts, sun visor and rear view mirror screws in now. It is a whole lot easier to find a screw head under the headliner than it is to find the holes.
Start at the front Center of the Windshield. Mark Your Centerlines, and if using a spray adhesive, mask off anything you do not want glue on. Seriously, headliner glue is some of the nastiest stuff to remove once dry. Have Acetone around to wipe any overspray off while it is still wet.

Keeping the material warm will help reduce wrinkles. My highly skilled assistants were up to the task.
Pull to the front center, and wrap around the pinch weld, use a piece of door weatherseal to hold it in place. work your way from the center out pulling forward and outward as you go. Hold the entire seam in place until the glue is fully cured. I did not do this once, and the front let go when I pulled the back. Once the front is secure and held in place, move to the rear window, and repeat.
Once the front and rear are tight and set, there will still be wrinkles running front to back. That is okay, they are going to get pulled when the sides get glued. If there are any wrinkles running side to side, it may not be tight enough. Have an assistant use the hairdryer constantly while you are pulling and it will help.
after the front and rear are secured, I moved to the drivers front. Again, masked off for overspray. At this point, I am only trying to glue the top rail, ignoring the vinyl that drops down the pillars, that will come later. Have one assistant put tension on the passenger side, the other warming the material, and pull outward starting in the front corner, then moving to the rear of the door opening. You may have to cut reliefs in the corners to avoid creases. TEST Stretch first, be cautious with your relief cuts.
Secure the top rail of the first door, and move to the other side pull and secure. Those wrinkles that ran front to back should be going away. If not, gentle heat and pull a little tighter. Not a bad idea to test pull and look to see where you might need to pull tighter.
Zig Zag your way back. I went drivers front, passenger front, driver rear, passenger rear, drivers cargo and passenger cargo. I will let the glue fully cure for 24 hours before removing the door seal material, and fitting the pillars.
Nice and tight, minimal wrinkles that should work out with heat and the pillars getting secured. Interior cargo lights installed as well.
