Other wise the silicone rubber might be available through automotive 
stores. It is available through aviation parts suppliers. It's the same 
stuff they use for engine heat baffles.  Might be a tad expensive 
though.  I don't know what they charge for it.  Try  a search on 
Aircraft Spruce, or AircraftSpruce, or  silicone rubber aircraft engine 
baffles.
