Here is mine in blue. Make sure you use a workable material. After you remove the liner lay the new fabric on top of the liner and work it into the corners. Spray glue on a small test piece and check if glue bleeds through. Fold the material in half and place weights on the fold line. Spray the material and board. Lay the material down when the glue is tacky to the touch but does not leave the board when you touch it. Have a friend help you lay the material down. With one person on each side, run your hand down the middle. Then from the middle work it out to each side. Try not to stretch the material but lay it into the corners. Rub the headliner down and ensure that all surfaces meet. Repeat for the other side. Try to let the headliner dry for a few hours before reinstalling. Good luck!!!
Wow thanks everyone for all the comments and tips for doing this! I was thinking of Dynomating it while I had the headliner down. Thanks everyone I will def take a ton of pics and let you all know how it goes. Still looking for just the right fabric for the new headliner!
