Thanks Fred, I appreciate the suggestions.  Do you have any suggestions
about how to test the bond strength?


Thanks spcialeffects for your input too, while the use of old glue is
definitely a concern for me at least I am able to test and verify
performance.  The bigger concern for me is that I'm building from a kit
that has had at least three previous owners.  I will check their work as
far as I can but there are some areas of the aircraft where I am unable to
see what they have done.

Ultimately any aircraft is a collection of trade offs and compromises and
this is just one of many.  Hopefully Huntsman will come through on Monday
with a reasonable price for 1.4kg of Araldite 420 and I can just buy it
---From them.
