Steps out-line

1. Remove Liner from Vehicle- Self explanatory, take your time.
2. Remove Old Liner material- The Fabric is attached to a foam but the foam tends to stay on the headliner board. when pulling the fabric try not to pull up but rather at a tight angle to the board. You can find videos of this on the net. Then rub off the old foam with your hand or scrape with a stiff brush do not be rough or apply too much pressure. the board material in my truck was made of a stiff foam sandwiched between a fiber glass paper sheet and a thin felt like pressed fabric, the foam gets very Brittle due to heat over time and if you press to hard can crumble inside or on the edges and the layer separate. Vacuum or use a blower if doing it outside.
