Agree that E6000 is much more pleasant to work with due to its low
viscosity. I was disappointed that it did not perform as well as the
Goop.

I asked the manufacturer if it is possible to thin the Goop but they
were not encouraging. I am guessing toluene would be the stuff to use
but I have not tried it.

I'd guess the same. Maybe put an ounce of toluene in a jar, drizzle
some anyGoop over it, and close it up overnight. See what damage it
did the next morning, and if the solvent did thin it, see if it still
works as an adhesive. Let's have another one of your wonderfully
documented tests, like the Rust Chronicles.


By the nature of the application I am trying for as thin a layer of
Goop as I can possibly achieve which is not easy.

Back in the day, when I was wrenching for a living, I used Gorilla
Snot (our fave name for 3M Super Weatherstrip Adhesive.) It worked on
everything in temps icy or steamy.


With all the other glues (epoxies - 4 of them, polyurethane, E6000, CA
etc.) I got initially good adhesion (I do 0.020" brass to appx 3/16"
steel) but if a corner separated the whole piece would literally pop
off. I turn the pieces to clean up the edges and sometimes the brass
would pop off on the lathe. Not so with the Goop. Even if I can get a
corner to peel off a bit I have to yank at it quite hard if I want the
brass to peel off the steel.

I haven't had good luck with brass, either. One of my wooden planes
had a brass sole epoxied to it. After a year in my shop, which is air
conditioned and heated, it fell off. That could have been the bubinga,
an oily wood, but I think it was the expansion differential between
the metal and wood.


I have not met anyone who can explain this, vendors, manufacturers,
other enthusiasts.

Do you leave a coarse finish on the mating parts so you get a good
tooth for the adhesive to grab onto?


I would love to know what is the chemistry of Goop and how it differs
from. e.g. E6000.

I'm sure Eclectic would be happy not to tell you.
