I've redone one of these headliners a few years ago at work, so here's my advice that the upholsterer at work told me as he loaded up his tool box and quit...
It was even blue if that helps my credibility at all... :lol:
Once you have the board cleaned up, if you have/get any cracks, duct tape them from the back side to repair it. If you do it on the side the fabric goes on, you'll be able to see the tape.
Lay the material out and start at the center, spraying the glue on both the board and the material, doing small areas at a time. Work your way outwards so you can follow the contours of the board.
Once it's all glued down, carefully trim the excess right to the edge of the board. Do not wrap the excess material around the back. It will mess with the fit, and will cause the material to start to pull up around the perimeter of the headliner.
Use a new, sharp razor to trim off the excess material, and to cut out the hole for your dome light. The visors you can pretty much just cut an X over the hole to allow the spring on the visor pedastal to pass through. Cut carefully from the backside, following the edge of the board to guide you.
Hopefully my words of wisdom
can be of some help... :lol:
