Metallic silver when pulverised looses its shine and becomes quite greyish and becomes more or less ineffective , and for spray applications very fine powder is needed.
If allowed in your country , your best bet is mica based pearescent pigments of which all metallic colours are available including many types of silver .
One such product is candurin from merck and senseint , hubie also make similar products .
These lustre colours can be applied spray or brush…it can also be used in a pan coater
