i removed all of the rotten insulation and rat nest and cleaned the top of the inside of the cab. any suggestions or different ideas to treat and reinsulate the cab about the headliner, i thought about treating it with por15. i have a roll of industrial insulation that is 3/8" thick with a backing that looks like vinyl top materail on the other side and also thought about cementing it in, also what kind of insulation and cement would you recommend.thanks
