I'm using spray-can headliner adhesive to get everything back together. That brings up my question. What kind of prep should I do to the shell, insulation and furry stuff before I attempt to glue it back together? Is there a solvent I should use? Should I sand the fiberglass shell? Will I have to replace the fuzzy stuff or the foil covered bubble wrap?
To prep for the re-gluing of the insulation to the shell I would, as necessary, lightly sand away any old adhesive on the shell, then clean both surfaces thoroughly with acetone or lacquer thinner. Let dry and apply new adhesive. For best results, and depending on your adhesive and accessibility, you may want to coat both surfaces (like a contact cement) before binding.
To re-glue the "rat fur" to the insulation, I think a quick cleaning of the insulation surface should suffice for good adhesion. Again, lightly coating both surfaces may provide best results.
