This has been covered before but not in too much detail so I'm giving it another shot.. I'm sound deadening my car and I want to deaden the ceiling. This will obviously require me to drop the headliner. Now many people have said to avoid this if possible, but what I'm really looking for is advice from somebody who has done it before. I want to make sure that I do it right and do it carefully. So removal as well as reinstallation tips would be really great. Thanks in advance.
