At this stage I'm not deadening the rear doors anyway my efforts will be focused on the fronts (I am going to do the outer and inner skins plus seal off the service access holes). I actually need to transfer the splits I had in my old car over at the same time so I will need access to a jigsaw etc for baffles anyway.
Hence my coming down to stickybeak. Depending how long I end up staying I will be happy to lend a set of hands to anyone who needs.
In the past I have used MDF sealed with spray acrylic paint to block the service access holes. Other people have used everything from masonite to sheet aluminium to polyethylene sheeting.
I had an idea recently and that is why not use that corrugated plastic sheeting that you typically find in collapsible cargo boxes etc? It's cheap, light, stiff, very easy to cut, and most importantly it is waterproof. Just cut it to shape, then gaffa tape it to the door and cover the whole shibang with sound deadener.
