I have researched interior paint until I don't know which way is up. Aren't the colors suppose to be flat? Is my paint flat because it is 50 years old? Was it gloss when new? I saw the Suburban with the pulsar gray interior and it was gloss. My paint store mixed the PPG pearl beige by paint code and it was gloss. I have seen vendors list their interior paints as "lacquer". I thought maybe that was to get the pre-rubbed out satin sheen. What don't I understand?
