Hi Vivek
Before gluing your neck I would try and clean your binding. It is major pain as kept on sanding through the neck finish and had to restain a few times to get a clean edge and then the truoil bleed onto it.
My best result was obtained using Tamiya modeling tape 6mm thick as this creates a really nice clean edge with the binding vs masking tape. Before you do your top coat cover your binding with tape and seal your finish then remove the tape as this will avoid bleeding. And paint on your first coat of top coat.
