To those who have plastic to cut out a new headliner board, where did you buy the plastic sheet? Ive looked everywhere.. someone on here did it on a ttop, cant find it now though.
it was me, with the ttop I got it at a place that makes vinyl signs. It is PVC foam board, the one I got is made by Versacel, great stuff. i used it to do door panels and the entire interior of the trunk. It is moisture resistent too.
