As I understand the technology, the resin really isn't that important
in the overall equation. Any bisphenol-A resin will generally work.
But the choice of hardner is crucial. Can someone help me understand
the chemistry here? Should I be looking at an amine based hardner, and
if so, which type?

Aromatic Amines
Aliphatic Amines
Cycloaliphatic Amines
Boron-Hydride Amines
etc.

Then there are "modified" versions of each of these, and they also
make and sell blends.

There are other types of hardners as well, and I don't understand
those either.

Can anyone tell me what a "normal" aviation grade expoxy resin
consists of? What about resources that will help me to understand this
so I can make an informed choice.

Thanks for any information.
