Sorry about that,,, here's a photo that shows how we are applying the panel lines and rivets. It's a technique used in the modeling Industry and we found that it works for us too. We use a hot soldering iron with shaped tips.
The heat transfers through the metal into the polyimer undercoat and it softens. Our metal just follows it down into the recess. It takes a little practice to get the depth right but we learned that with an adjustable temp on the iorn makes it much easier. We also use thin aluminum that we buy in sheet, cut it to size and use it as a straight edge.
The raised panels are nothing more than another layer of metal.
