Silver can be a tricky one to get a good deep shine on, and you won't be able to shine the car like say, dark blue or black.
However, you can still get an excellent finish.
I'd polish with Clearkote Vanilla Moose glaze, then use either...
an all in one product like Klasse AIO, as your glaze/sealant,
or...
split these into individual products, as you will get a slightly deeper shine with ClearKote Red Moose Glaze, sealed with Poorboy's EX-P. You could even try Poorboy's EX, meant for darker finishes, as this can give a 'pearled' style deeper finish on light colours. This is unusual, but a few people in the States have tried it with results they're pleased with.
Finish up with Optimum Car Wax, a great final stage on silver, and excellent to use
