I test water-fastness of Sharpie Paint Pens in both Oil-based and Water-based formulas, after I’ve sealed them with a clear acrylic matte sealer. I use Sharpie Paint Markers on a rock and on painted metal boxes and then show you how to make your design permanent to hold up to water and every day wear and tear.
