Time to redo the headliner again... Backer board is all there and if I am super careful it could probably survive another round of removal and reinstallation maybe. But the wheels are turning inside and I have the idea what about a layer of fiberglass on either side to encapsulate and reinforce the board ? Sure there is the weight penalty but maybe if nothing else it might dampen the road noise slightly. For putting on the new fabric i really want to vacuum bag it so the fabric will suck down nice and tight into the corners.
questions, comments, ideas ?
