Did you clean the box and sand it a little bit before to apply the primer ? Sanding will help the primer to "catch" the piece.......same after primer, you can gently sand it to use the paint to fix to the primer.......

No, I didn't make one of these Razorback box but I made an explosive arrow but, often, when the primer doesn't stay, it's because the piece is dirty or oily !! I usually use automotive primer and paint because they are stronger.
