Well I just found that the Honda ShinEtsu silicone grease
works great. I forgot I bought this stuff a while ago and it fell behind the table in my garage.
Just tried it on our 6 month old Alltrack that never had any seal treatments of any kind and had started creaking even more than it had as the weather cooled down here.
I used a rubber glove to go along the felts to clean any fuzz off then I did a quick 99% IPA wipe of the felt and rubber to rubber surfaces along the top inside seal of the door and around where the window rolls up to get them clean.
Applied a bit of this stuff using the glove to the rubber to rubber surfaces and with a q-tip and my pinky up the sides of the window track on the drive door. Backed out of my driveway which makes my chassis flex nicely and not a sound from that door. I heard all of the other doors though!
Did the rest and took a spin, never knew an MK7 could be so quiet. Can’t wait to get my GTI back from the dealer due to getting a new head so I can apply it there.
