Making a rustic walking stick and needed to epoxy a long narrow crack. Mixed some T88 and put the stick in a vise with the crack upward. Applied some epoxy and left it for an hour or two. Came back and the epoxy had sunk into the crack of course. The mixing cup was nearby with some leftover epoxy that was still buttery. Just for kicks, I applied some of the buttery epoxy over the crack using the popsicle stick. Came back after an hour or so and the crack was filled level. Maybe everyone knows this but I didn’t.
