Hey Guys
Just bought 6 sheets of this material.
http://www.perfectfit.com/15347/154532/Chipboard-Car-Panelboard/Kraft-Tan-Wateproof-Panelboard.htmlIt is used by Ford, Chrysler and Kenworth for interior and door panels.
I'll be using it for door panels and headliners in my 51 panel ......
I intend on covering it with foam backed headliner material for headliner areas
and short napped carpet for lower door and kick panel areas.
