Silver isn’t nearly as difficult as Audi/VW Imola Yellow :wall
My experience with silver hasn’t been too bad. Polish the paint to flawless (or near flawless) finish. With silver in particular, I prefer 1Z polishes. There’s something to 1Z which allows metallic flakes to pop and gloss to flow fender to fender. Top with a quality sealant to not only protect, but also amplify the brilliant shine. Here’s the kicker . . . add several coats of carnauba (pure or synthetic hybrid will do). My own personal preference is #16, PW, or 1000P. Voila! Depth, fantastic shine, crisp reflections, and dripping wet gloss.
