Found it... CP 46 page 7 (knew I'd seen it somewhere!)...
Ralph Gaither, Safety Officer for the Navy and a high time VariEze
pilot, reports what he considers to be a possible flight safety problem
for pilots using a product call Thermeeze Tape (high strength ceramic
tape). He purchased this product from Sport Flight in Florida. Ralph
installed this tape per the instructions, to his exhaust pipes (this EZ
already had over 800 hours of flight time). Within 100 hours the
cowling was burned completely through in close proximity to the ceramic
tape. In addition the tape crystallized broke down to a powder and
generally fell apart into the cowl.
Ralph is very concerned that with this condition and the use of
carburetor heat, some of the powdered ceramic tape could be ingested
into the engine, possibly causing engine stoppage. In addition to
this, Ralph noticed no benefit whatsoever to the operation of his
engine.
RAF has never recommended this tape or any other similar material. If
you are using it, we suggest an immediate, careful examination of the
tape before next flight. Sport Flight has been informed of this
problem.
