The one you need is the 303 Aerospace Protectant. About $55 a gallon on Amazon. But, although it may seem expensive, it's 128 oz, which equals 8 bottles of 16 oz regular protectant or cans of silicon spray. And, as noted, a little goes a long way.
As a side note, 303 is the perfect stuff to use on your vinyl decals. You do not want to use a carnuba based wax on vinyl decals or wraps as the carnuba will actually dry out vinyl over a period of time.
