How did you solder it and with what? Does soldering not remove the galvanized coating?
Soldering duckwork seems pointless unless you just like soldering for the
hell of it. You can buy duct in L shaped sections that are pre-crimped and
form nice rectangle or square sections. Screw them together and cover in
the aluminum tape. They also make some sort of putty-like stuff for
sealing ducts that comes in tubs, like drywall joint compound.
