I have a stamped antique gray driveway. I had rust spots so I applied a rust spot remover which left white spots. I have purchased your Ghostshield sealer, which is to arrive Monday. Priot to applying this concrete sealer. I need to make a uniform look on the driveway with a stain, which is currently a lite grey. What would you recommend for the fact that I don’t intend to change the color dramatically, but rather just cover the white spots to get an even look. Could I apply just one coat of the stain sparingly over the entire 3000 square-foot surface prior to ceiling the concrete?

Stain can react differently with tinted concrete so I would stay with a light color in only the area you need color to see if that gets closer to the rest of the driveway vs Staining the whole driveway and potentially having a spot that is still lighter.
