Just wanted to share this website. A bit on the pricey side but I bought a set for my black alu panniers and top box. Fitted them myself. Bit of masking tape a stiff ruler and patience. Stickers are very durable quality and very ''thick'' material. Had the power wash on them after the bike got filthy and they wont budge.
