Regarding: " Lancair IV kit pre-buy inspection...  I think they closed all
surfaces with epoxy and flox instead of hysol... Pass it by.  This is a
major structural concern.  Bill Harrelson"

Hmmmm...  at our Legacy builder's assistance workshop I asked Mark Mahnke
what the considerations were for use of epoxy/flox vs. Hysol.  Mark said the
only difference is when you need more time to work.  Since then I remember
someone on the list saying that the peel strength of Hysol is greater than
epoxy/flox.  

I'm wondering, though, just what are the latest opinions of the experts out
there on what applications are most appropriate for Hysol and epoxy/flox?

BTW, we closed out our wings, horizontal stabilizer, and elevators with
Hysol.  Our fuselage to center wing section bonding and load path
reinforcements were with epoxy/flox.
