Adhesion method/application of white bond type (Cybinol, etc.)

Since it dries easily and cannot be bonded once it dries, apply 2 to 3 thin coats of bond so that the bond does not stick out from the bonding surface, and paste them together so that their rubbed surfaces match.
If the bond does not adhere well, or if the silver side is to be adhered together, use a dresser or similar tool to roughen the surface.
