I just bought another quart of furnace cement, and think I'll be very liberal with it on the BGE firebox. One thing that I did on the firebox of the Medium IK was to set it in my stove and gradually raise the temp for a couple hours to cure the furnace cement. It was in at 500* for at least an hour with no damage(my wife wasn't thrilled) I don't think the firebox from the Egg will fit. I was looking at the temp rating for the Rutland gasket sealant and was thinking it might work on the joints. Does it dry hard or flexible with the rope gasket?
An old carpenter told me to drill a small hole at the end of the cracks to keep them from spreading. Worth a try?
