I finally found a decent headliner in a local salvage yard. The cloth was sagging and the nasty foam was disintigrating so im gonna redo it. The wind got to it on the way home so now I have some fiberglass work to do before it gets cloth but my question is what did you guys that redid your's use to clean the backing? I have all the cloth and foam off of it now but its really sticky and some of the foam has smeared to the point of not coming off at all. These are hard to find around here so I dont want to ruin this one with water or a solvent if there is a better alternative. The adhesive and new cloth/foam is already taken care of I just need some help cleaning this nasty thing. Thanks in advance.
