Homemade Epoxy Putty

This photo shows the materials I use to make my own epoxy putty. Commercially available epoxy putty is often too stiff to be used easily and tends to dry out and become useless when needed most. I've found this homemade stuff works well. The 1:32 Cessna 310 model can be picked up and held horizontally by grasping either tip tank; this putty works great when a strong bond is desired.
