Quick-cure Epoxy

Dear Orval,

You're right, of course. Any epoxy, fast or slow... CAN react exactly
as you've described. But the reason can usually be tracked back to
some problem with either the chemistry of the components or a problem
with the ratios. For example, more than thirty years ago I recall
using lots of "5 Minute" epoxy on at least three of the Varieze's
fabricated here in San Diego county.

Also, I have found (from model airplane building) that the chemical
resistance properties can be different from the quick to the long setting
epoxies.

The quick set is not nitro methane resistant, but the long setting resists
just fine.
