Hello all, I posted this on cherokeeforum and did not receive a reply so I figured I would try my luck over here. I am getting ready to prep my car for herculiner and was wondering if I should remove the heat shielding/noise dampening material or just apply over it. I have a 97 and it is on the transmission well and floor area where your feet are. Also there is a thick amount of it in the trunk as well. If I need to remove it anyone have any recommendations as they are stuck down pretty good?
