Signs 40cm and under can be painted with spray paints, including Metallics, or with Paint Pens in these colours
Example Paint Pen photo’s
I use premium American Metallic spray paints. The Metallic effect depends on the lighting and angle. The results are much shinier than the pictures show, as it’s very difficult for the camera to properly photograph this shine.
All of these photos shown below were my products or samples & photographed by me.
