That duct wrap worked so well I decided to rebuild the entire heating and A/C duct system replacing all the foam gaskets. Here are some pics of the process...

Here's the blower housing. you can see how the original foam has deteriorated. All the vent flaps bang around and don't seal properly, and the foam breaks up into dust at the touch, which probably ends up all over the interior, or better yet your lungs...








Here's a comparison shot...


and completed..




The heater core housing was a little more involved, with i think four different flaps...








And then finally reinstalled...


This was definitely one of those "while i'm in there" kind of projects. It took a while to get everything cleaned up and rebuilt but it was worth it. The controls feel nice and tight and the vents open and close with a nice muffled thud instead of the slap and bang that they used to. I highly recommended doing this next time you're "in there." The $6 roll was more than enough for the whole thing.
