So I've gotten tired of asking the SC to fix the rattling cross-member trim on my pano-roof - the one above and behind my head. The rough Arizona roads make the car sound like my old '62 VW split-window bus. Okay, that was mean, but I've been driving a lot this week Yes, the car is my third love, but I have to fix this noise. Any suggestions? Silicone tape around the wires? Spray foam? How do I make sure the anchors stay tight after taking the thing off and putting it back on multiple times?
