So apparently i like to make my life harder than it needs to be. I wasn't happy with how my tests turned out regarding painting the binding to cover the stain pulled into the cracks, so I decided to rebind the body. The binding has come off relatively well so far, but even though i was taking as much care as possible to not heat the body too much, I've noticed the crack near the neck joint has been opening and closing fairly significantly.
Does anyone have any advice on how to stabilise this prior to clear coating? The last thing I want is for it to crack the finish over time.
