beefy_hdi- Now that you've probably searched and been overwhelmed by all the info...
Note that silver is almost always (my Jag's lacquer being the exception) just another clearcoat paint, and for the most part clearcoat is clearcoat.
IMO the big trick with silver is seeing all the little imperfections (scratches/"swirls", i.e., "marring") that cause light to refract instead of reflect. Once you see those flaws, polishing them out will make your silver look a lot better.
A simple step in the right direction would be to find something like Meguiar's #80 or some other mildly abrasive polish.
A perhaps even *simpler* step in the right direction would be to get some AutoGlym Super Resin Polish. Use that and then apply either their Extra Gloss Protection (or whatever they call it these days) or some other wax. The SRP is good stuff and pretty easy to use.
