I have a Platinum Silver Metallic Subaru,
I've used DP Max Wax over DP Poli Coat and it looks great. I can't say that it has a wet look to it but it has a great shine and really made metallic flakes pop. I've also used Dodo Juice Light Fantastic soft wax that also had great shine. Pinnacle Signature Series II is next on my list to try.
