The only way to eliminate this now is by replacing the pin and roller bushing on the body side as it likely has flat spotted from the hinge sliding on it rather than causing it to spin.
Lubricating the hinge roller bushing is a common mistake and once done, is nearly impossible to reverse.
The bare edge of the hinge assembly on the door side is normal and should not be painted. When a hinge on our Av's begins to make noise it is because some type of lubricant got onto the door side of the hinge mechanism providing a reduction in friction required to roll the bushing on the body side of the hinge. Lubricating this bushing and hinge are the absolute last thing you want to do. The right move is to clean it w/ a heavy solvent like brake parts cleaner and dry it thoroughly. The hinge and roller bushing are designed to be dry. The arm on the door side creates friction w/ the roller bushing on the body side causing it to spin as the door is opened and closed. Lubricating these parts causes the arm to slide along the busing as opposed to rolling it and creates a flat spot on the bushing. Once your lubricant wears off, the arm then continues to slide along this flat spot making all kinds of noise and/or creating sticking points when opening/closing the door as is will never turn the bushing again due to the deformation caused by the hinge bar sliding.
To each his own, but if you consult your dealer or any GM master tech, they will tell you under no circumstance should you lubricate the door hinges, you're only asking for a lifetime of creaking/cracking and constant need to re-lubricate if you do.
