An automated priming system and method for applying a liquid, such as a primer or treatment liquid, to a substrate provides a surface variation sensitive applicator assembly which applies a constant pressure to the substrate during the liquid application process and, therefore, provides a process which achieves a more uniform application path and coating thickness. The automated system includes a robot and at least one applicator assembly. The applicator assembly includes a base and an applicator tip mounted to the base. The applicator tip is adapted to receive a supply of liquid. The robot holds the base of the applicator and positions the applicator tip on the substrate for applying a liquid onto the substrate. One of the applicator and the robot is adapted to apply a constant pressure to the substrate during the application process. The method provides supporting a substrate, holding a applicator assembly, positioning the applicator assembly on the substrate, directing a liquid on to the substrate through the applicator assembly, and storing the applicator assembly between applications in fixed location. Optionally, in primer applications, the applicator is stored in an environment which prevents premature hardening of the primer in the applicator assembly. For example, the applicator assembly may be preferably stored in docking station, which optionally includes a reservoir for holding a primer solution solvent and a vapor port in communication with the reservoir. The applicator is stored in the vapor port such that the solvent vapors prevent premature hardening of the primer solution in the applicator.
