The surface of epoxy solar panels get cloudy and opaque over time. I am trying out a repair using the Scratch Repair Stick. Using the clear coat marker, you can quickly recoat the small solar panel. Use a sand paper to remove the buildup on the surface of the solar panel before you recoat it. The clear coating hardens with the sun and as it is meant to be used for auto scratch repair, the coating should be UV resistant. The repair stick is about $6.Click here to subscribe to this channel: http://www.youtube.com/subscription_center?add_user=wtam69
