Hey folks,

From the factory, the aircooled vans have all the heaterboxes, flapper
valves, and associated metal tubes sealed at the joints with somekind of
black sealant that I assume must be high temperature resistant.  What is
this stuff, and Where can I get some?  Also, does anyone know of a
source for the pink rubber discs that go in the heater valves?  One of
mine has gone brittle and cracked.

Thanks.

Greg.
