Default thinning two part epoxy?

I have a small project that needs epoxy to bond one section.
Unfortunately, the area where the epoxy needs applies is narrow. The
last time I tried it, I attempted using a cut off syringe, like
diabetics use, except the needle was cut off and the cylinder cut away
until is was maybe 1/8 to 1/4" thick. Unfortunately, I was not able to
draw any of the mixed "5 minute" two part epoxy into the syringe as it
was too thick.

The epoxy I'm using is just the small, twin cylinder type that premixes
in either a small tray as part of the package or in something else. I'm
just wondering what I can do to lessen the viscosity without
compromising strength or other properties when dried. I was just
thinking of putting the package under a heat lamp set at like 110 F for
a couple of hours. Thoughts and experiences welcome and thanks in advance.


How much strength do you need? Acetone will thin it but is going to
affect the strength and curing time. Another option might be pourable
epoxy. Hobby shops generally have it in small quantities for decoupage
projects.

Heating may be the best idea if you're fast. From the description you're
not going to be using enough volume where the exotherm will be a problem.
