Mark,
Many brands of epoxies come in uses for laminating and structural purposes.
The finish resins will have a trace amount of wax added to the resin; The
wax will form on the surface to preclude moisture in the air from becoming
absorbed in the curing resin. This trace Wax in the cured resin

Is it cold or humid? You may want to try a heat lamp to get rid of the

The ratio of Resin to Hardener for AeroPoxy is 1 part Resin to .27 part
hardener and this is by weight, which I forgot to mention before.
The ratio is the same no matter what you are using it for, Micro, Flox,
Fiberglass, Carbon Fiber. It has to be the same.
Put your cup on the scale and set it

Can Aeropoxy, part A resin be rejuvenated if it has gelled? I know that T-88
can be brought back to use if it crystalizes by warming. Is the same true for
Aeropoxy resin or should it be discarded. About a third of the volume has
stiffened into a gel.
Resin and hardener were purchased
recommendations and flew their airplanes for years.
I'd say, get your temps up and see what develops.

The usual suspects for uncured area of epoxy are inadequate mixing,
expired shelf life, surface contamination or incompatibility with
something in the substrate. Assuming none of these, the epoxy should

How humid is it in your area? Has been real bad here and that will affect
