Im sure someone else has dealt with these same rattles as i have any suggestions. My rearview mirror and its not that the screws are loose. Ive been thinking about putting some foam inside where the plastic cover but havent tried that yet. my front door panels need sound deadening but rear deck. I redid to get rid of rattle from the board that went across but when i built my own one the damn brake light now has nothing to be attached to. so it rattles. does anyone know if that brake light is mandatory on all cars? Also for trunk lid rattle have yall used spray on deadener on sheets. my car is on geocities.com/azmalu click on bottom of page maybe you can understand a little better what i am talking about then.
