5" backing plate - 6" pads . Wash it and clay it , then go over it once with a paint cleaner and the blue pad .
Silver can't be made " deeper " usually so a wet lsp is best . I would say UPC + UPP would be best .
AIP +
SG a close tie for appearance and more durable .
Vanilla Moose + Carnuba Moose wax for good shine and good protection cheapest of the 3 combos .
Then buy a compatible qd spray and some quality microfibers .. Clearkote's Quikshine works with all of them
