To follow up on the removal of the adhesive, Brake Cleaner works wonders. Gently soaking a small section at a time and giving it 5 - 10 seconds to settle in and the adhesive just brushes away with a hand held wire brush. It takes it back to the base board. I was able to remove half of the headliner in two times through "Stairway to Heaven". Hey if you're going to inhale fumes go with the mood!! Now, who knows how long Stairway to Heaven runs?
Another tip. Don't use any kind of rollers or tools to lay the new cloth down. After experimentation, again, I found that just starting at the center line of the headliner and working out in 6" sections using an open hand and gently pushing the cloth out it turns out perfect. Check for bubbles being sure to look from all angles. Lighting will hide some bubbles.
Anyway good luck to anyone who tries. It really isn't too hard. Mine was a one day project including trying different techniques.
