[Amps] Silicone Rubber Chimney Adhesive?

[Jeff Maass]

What sort of adhesives work for making chimneys out of silicone
rubber sheet?

There are dozens of "flavors" of RTV / silicone adhesives out there.
I have on hand tubes of "Permatex High-Temp RTV Silicone
Gasket Maker" and "GE Silicone II Household Glue", both of
which have temperature ratings that match the high-temperature
silicone rubber sheet.

One person suggests "Permatex Ultra Copper". Is there an 
advantage to this adhesive over one of the ones mentioned above?
