Is Amorall known to darken interior vinyl panels over time and repreated use. I had the driver side upper panel repainted because it had a tear and it was repaired. The repaint is good, but it is a slightly lighter blue than the upper panel on the passenger side. That could be because the paint/dye is original and over 20 years old. I don't want to repaint the driver side. This will take out texture and the color is close. Is there a vinyl product like "back to black" that will darken it slightly?I have heard about Forever Black, but I know that it is a dye and may give a shoe polish kind of look. I just want to darken the area slightly. I have used of all things, Olive oil...it does seem to help. Leaves a nice shine. Just wondering if there was anything specifically designed to slightly darken vinyl. thanks
