Shot laquer and pore filled bass.
The soundbox fell from four feet and the trble upper bout binding got compressed, the top cracked and popped off the body. To repair I cut the top seperate from the binding with a razor and dumped a bunch of superglue in there, clamped close for 15 minutes, then spread the crack and stuck some titebond down in there, then clamped it closed for 45 minutes. It's all good, only sign of damage is the flat part of the binding, which isn't too noticable.
