I use a multi-layered approach for all minifig shields. I start with a plastic-adhesive metallic spray paint and finish each element with a clear coat spray. All designs have been created electronically and are generally based on historically accurate designs that have caught my eye. *For resin-printed shields, like all resin-printed parts, you should expect some occasional variability in appearance or fit. But the machines & tools have improved so much that most hobbyists and collectors feel that fidelity, precision and quality are typically excellent.
