Quoting theevozero:
I've seen what he's talking about. Not real sure what the benefit is for using that material. But you could definitely lay it over a trashed liner for a face lift. I just wish I has liner left.
Thats the good part. You dont need perfect liners. You can anything to fill in missing pieces, such as an old license plate to make the shape. Use pop rivet to hold it all together then glue the "carpet" on. Once you cover the liner you won't know what's underneath it. Bam, just like that you got new looking liners. Only drawback is that the material can fray when pressure washed too close.
