Silver needs to reflect, I find Four Star UPP and Pinnacle SSII as well as Wolfgang Fuzion seem to help metallics sizzle. So I would use them to protect but first amp up the reflection and gloss with the Menzerna polishes. If you really wanna go pop wild, use Menzerna 085rd and finishing pad after both to really jewel the paint then add the wax or sealant above.
