    Does it exist at reasonable price?

    2)good bond to metal to lock out condensation
    3)Goldilocks levels of tough, flexiable so it won't separate if something bangs on the thin metal from outside, or metal feels some vibrations.
    4)able to cut or remove with a bit of effort.
    5)OK to cover wires and pipes with it, including after first layer of foam is applied.
    6)patchable and workable, sort of like sheetrock mud (in addition to sprayable). Maybe spray some wet foam into mudder's tray and apply with taping knife tool.
    7)good bonding to other materials. do a base coat on metal, then later smear some foam on back of 1/8" doorskin or even fabric and glue to base layer.
