Absolutely, though keep in mind its not so durable. granted it would be protected by whatever its cast in, though for the money you would be spending on silver nitrate, ammonia, and sodium hydroxide, you won't be very far off the cost of a 5 litre replica chrome plating system, which would set you back around £90.00 from gateros plating. Much more durable and great results
more over, the fumes you give off when doing this, are not good! so be sure to have good ventilation if you are planning on giving it a go.
