Does anyone have any idea what these black stickers are on the ductwork? They felt slightly tacky to the touch. I thought they may have been covering holes, but they were not. They were on all of the ductwork, and I have never seen this before. Any ideas would be appreciated. Thanks in advance.

Maybe cross breaking wasn't enough and the are to help keep the expansion/contaction noise down. Never seen them before really...

Larry's got it.
It damps out the duct pop on blower start up and shut down. http://www.acousticalsurfaces.com/hv..._vmax.htm?d=26 "Never underestimate the difficulty of changing false beliefs by facts." |

Never seen it either, but that is what came to mind first too.
Possibly a thinner sheetmetal than normally used and the duct was drumming with the velocity of the air.
