Okay, Rob says he got headliner fabric at Joann's (of all places, lol). They have it in several colors, it is foam backed.
You need a philips head screwdriver. You need to remove everything in the headliner (visors, lights etc.). Remove all the plastic trim surrounding the headliner so you can get it out. Sometimes there are metal clips holding it up, but usually it will come loose when you start to take off the trim and you can see if anything is holding it up still. If there is a light you need to disconnect the wires. Scott is handy and can do this easily.
So, you take out the headliner piece and use it to figure out how much you need buy. You need one can of spray adhesive - something that can handle high heat since the sun beats on the roof. Scotch makes Super 77 or something. Try an auto part or hardware store for this. 3M makes a headliner adhesive but Rob couldn't find it.
Just like the PP said, you have to scrape off all of the disintigrating foam and glue from the previous board that you took out so the adhesive has something to stick to. Use some kind of stiff bristle brush and get as much off as you can. The spray adhesive is a contact adhesive, so you spray, wait a little bit and stick the headliner down. Rob says to lay the whole big thing down, then roll back half and spray it, wait, then stick it down. Then do the other half the same way. He also says to pay attention to how the edges are done when you take it down, and try to put it back the same way. IOW if it's wrapped around the edge and glued for an inch or so, do that and then trim off the excess. If there is a light hole, you cut an X and fold to the inside. Rob says it will be pretty obvious how they did it when you take it down.
Whichever side of trim you took off first, you might have broken a clip or two. Rob says that you can borrow a clip or two from the other pieces when you knew how to take them off,lol. You don't need every single clip on every piece, as long as it's up solidly. Then, installation is the reverse of removal. If you break the board, you can use duct tape to fix it since it can handle the heat. If there are electrical wires, you can reattatch with duct tape also.
Okay I think that's it. HTH! You can call of course if you want to talk to him about it
