Hi Brian,
I'm finishing my basement this spring and want to seal my ductwork joints as they are really leaky.
Most ducts are running in the floor joist cavities and space is limited. I've taped as many areas as the space allows but still have many leaky areas. I was thinking of using mastic to seal the joints before I drywall as I could get a paint brush in to some of the tighter areas. Do you have any thoughts and were can I buy the stuff. The big box stores don't sell it.
Thanks for your help.
Scott.
