A few years ago I called Dexter-Hysol to determine which Hysol to use in a
Monerai glider that a friend and I were assembling.  The problem was that the
originally specified Hysol was unavailable -- the old version contained
asbestos and was superseded by another version.  This new version (9430) is
what is included in the Aircraft Spruce catalog.

Dexter has a fax-by-phone system whereby you can request data sheets for their
products.  Interestingly, 9430 is a product of their commercial division in
Seabrook, New Hampshire, not their aerospace division.

During this process I learned that each Hysol is quite different and should be
researched carefully before substituting a different version.  9430 and 9339
are not the same.  They don't even look the same.  (I have their data sheets
somewhere, but you can probably find them faster by phone than I can by
digging through my storage boxes.)  While 9430 is good stuff -- I used it on
the Monerai wings and tail -- I wouldn't use 9430 in place of 9339 unless
Lancair gives their approval.  Which, to my knowledge, they haven't.
