Thanks. That sounds like an idea worth attempting. Little to lose.

Are you talking about those two-part epoxy putties that you massage
together to blend, then place where needed?

To my ear, "massage" sounds insufficient. At least for PC-70, the
weaker epoxies in the syringe, and others I've used, I fold one part
into the other part over and over and over again. From different
angles, etc. 20 times maybe. In the middle of this I swirl it all, in
each direction, all to get a good mix.

Just making sure the color is uniform doesn't seem sufficient to me,
because I think our eyes average out the color and it doesn't mean it
is mixed at the small level. (Like one doesn't see the individual
red, green, or blue dots on a tv screen or in the funny papers, even
though they are there.)

And when I haven't done this as well as I describe, at least twice it
didn't harden as quickly as normal. Maybe it never hardened. The
second time this happened, I kept the remaining mixture for a couple
days and it never got very hard.

Understand totally about not leaving the pin extended while curing.
