Last night on "Ask TOH", they had a guy who showed how to seal FHA
duct work. Are there foil tapes available to a homeowner that are
very high grade? Is the stuff at the BORG good enough to do the job?

As long at it's FOIL and not that grey cloth stuff you should be fine.

One more...this is heating season in NE. How long does it take for
duct sealing mastic take to dry?

The foil is pretty sticky to start with. Never had a problem with it letting
go at all.
