Ok, it sounds like these solar panels & closing blinds, shades, & drapes during the day are the best precautionary measures to prevent sun damage like this. I'll go to Leather Magic's site & try to learn more about the SPF 80 product. It sounds like something I'll need to apply lightly(on an aniline pull up,) & just get in the habit of closing the blinds during the day when I'm gone.
