I have a cavity in my rear hatch of my 02 Ford Escape. Im buying a case of OC703 for my 4 doors and imagine Ill have some left over, would this be good for the hatch door or am I better off with stuffing every square inch with the denim fill? Ive already stuffed all the cavities I could with denim fill in the cabin floors and pilars, laid a layer of the sound deadener, radiant barrier, MLV and the carpet. It sounds all right, but I expected better. I havent done the doors yet so Im hoping thats the reason Im not impressed. My plan for the doors is deaden, ensolite, OC703 wrapped in 1 mil, abs panels to close off holes using threaded rivet inserts to bolt it down, more deadening, and hopefully have room for some MLV hung from threaded rivets. The panel itself Ill deaden and/or ensolite if I have any left over.
