I thought I had a rattle in my headliner. My dealer was great and put some padding inside to make it tighter and more secure . It seemed to help for a very short time. However, it returned and after a road trip I believe it is in the headliner, but directly above the rear side window. I tried to squeeze some felt in there because there is play there too. However, there is very little room to push something soundproof inside. Any ideas on what is super thin that I could jam in there to help soundproof the rattle. I appreciate the help in advance!

 

Some pics would help

 

Pictures of the headliner right above the rear passenger window is the same on every Porsche, so not sure how a picture will help. Right where the headliner meets the the quarter panel widow. That is where I need the squeeze something thru...

 

Wrong, it is not the same on every Porsche so post a pic or two if you want help.

 

Very true, not a Targa like yours...my bad Bob.
