Heating the epoxy to thin it sounds good, I'll have to try that. What I do to get it down in the crack is:
1. Spread the crack abd prop open with a toothpick(s)
2. I use relatively slow drying epoxy and force it down into the crack with a burst from an airhose (at about 100 psi). I usually do this several times.
3. I pull the toothpicks, wipe off the excess glue, wrap wax paper around the repaired surface and then tightly wrap with surgical tubing (I've also used an old bicycle inner tube).
4. After the partial cure time is reached (it usually gives partial cure times and full cure times on the glues instructions) I unwrap everything and using 0000 steel wool I remove any additional excess glue thats squeezed out of the crack. Then I rewrap it and leave it 24 hours before I unwrap it again.
I've successfully used Devcon glue and try to use a glue with a multi-hour cure time.
