I have done this for so many years with good results so I thought I would share with the forum my VB replacement technique. I buy the heaviest mil clear plastic (opaque really) that I can find. I then mount a series of velcro 1 inch strips on door following the original glue line. I mount the velcro so that both sides are adhered and I peel off the paper strip to expose the adhesive on the VB side. I have a large rectangle of plastic sheeting pre cut ( 3'x4' roughly) and press against velcro adhesive starting at the top horizontal side and then move top to bottom, side to side creating tension so there are no wrinkles. I then take an exacto knife and follow the contours of door panel cutting away excess plastic and then cut out the various areas for door panel mount clips (make an x with exacto knife) door handle mounts, etc. and voila done and not prone to tearing for future R&R work. Why Velcro? In the future, when you need to go back into the door, you can carefully detach velcro without destroying VB so that you can lubricate regulators and perform other repairs easily. Re-attach velcro and VB is resealed. Makes maint. much easier and will last longer than original VB material. Good luck!
