How to Spray Headliners
A sagging headliner is a common problem that many people have with their cars, particularly the older models. It is nothing more than a board with a piece of fabric held on by glue, and can be easily be repaired by yourself without taking the car to a repair shop.
How to Spray Headliners
Take down the headliner by removing the dome light and any other screws that is holding the liner.
Remove the fabric and scrap glue off of board.
If the fabric is not damaged, use glue adhesive spray to reattach the fabric to the board. If the fabric has holes or is worn, it should be replaced with new fabric.
Spray glue adhesive onto the board and attach the fabric. Attach all of the corners first making sure that the material is taut before smoothing out the middle.
Set the headliner aside and allow the glue to dry before placing it back in car.
