[Healeys] Hylomar

[Dan Stromquist]

Mike:
I to did some research and wound up purchasing Hylomar from a local supplier
Goodson for $24 (mostly shipping) and now I see the identical product in the
Moss book for $8.95 part #221-556 (package looks identical).  I called a
distributor from a website I found, which name escapes me right now, and
they told me the same snooze is repackaged as sold in the UK.
Regards,

Daniel A Stromquist

There was a recent thread about difficulty in obtaining Hylomar, so I  
did a little research of my own.  Background: Hylomar is a non  
setting sealant developed to a Rolls-Royce R&D specification.  I can  
confirm from my 43 years with Rolls-Royce that it is used a great  
deal in military aero engines, and it works very well. Hylomar web  
site data shown below.

US military repair bases that look after RR aero engines have  
certified an alternative -- Permatex 1372, presumably because it was  
cheaper and more easily available in US.  Reports are that in many  
years of operation there have been no leaks as a result of sealant  
failure.

Hylomar is still available in UK and there is a later automotive  
version  - Hylomar Universal Blue Racing Formula Gasket & Jointing  
Compound

 From web site
"SQ32 was the original name of the R&D program at Rolls Royce that  
led to the development of Hylomar Universal Blue. PL32 was the  
original product name, and was available in Medium (PL32M), Light  
(PL32L), and Heavy (PL32H) grades. Hylomar Aerograde superseded these  
grades in 1985, but the references were retained in some  
specifications."

Hope this helps, at least you can seal some of the leaks.  But then,  
what will happen to the built-in Healey oxidation retardation liquid  
dispersal system (HORLDS)
