I'm wondering if this is common? Anyone else?

huh? like, what kind of foam are we talking about?

OH NO YOUR CAR IS RABID!

there is foam behind the vent....around it

the foam is used to seal the air ducts together. it is common, and holds air in well, it also keeps them from rattling

I guess a description would have been helpful. I assumed everyone had it and was just joking about starting that thread. It is really thin brown foam. For the last three months I have been finding it randomly on my seats and wondered - WTF. I logged in to ask about sealant adhesive prepping for my Telson spoiler trimbut got off track.
