Gazmondo, you have my utmost sympathy, that is horrible. I hope once cleaned up it becomes bearable.
Kyle, there is a TPI that encompasses the air vents, soundactuator and various othe bits whereby they order in a kit of insulation and place in various places in these areas.
i havnt the TPI number but was shown the documentation which shows the technician where to place everything.
They need to remove the side air vents which i was a bit concerned about, but they use special trim remover tools and you would never know it had been done.
I noticed there is an updated graphic on the replacement visor, still looks sh1t though....
