It's important to handle it every day. Oil it as needed. Keep it property humidified so it doesn't crack. Never let others handle your rig unless they know their way around it and aren't likely to drop it or crack the headstock. And remember, the sound it makes is more important than how it looks. Don't worry about peeling or finish checking. Eddie Van Halen is famous for making great noises, but his rig looked like it had been tied to the bumper of a truck and driven down the strip in Vegas.
If you notice any warping along the neck, it's likely that your wood is unstable. Seek qualified help immediately.
