[Harp-L] plating for chromatic mpc. Silver or Chrome?

[jon kip]

I need to get about twenty round-holed mouthpieces for my hohner deluxes re-plated....can use chrome or silver, and will be cheaper than buying new mpcs.

So what I'm looking for is a type of plating that will be slick, long-lasting, and, if possible, that will give me Eternal Life. 

But I  will settle for very slick and long-lasting, if that Eternal Life thing isn't workable. 

So Chrome or Silver?

thanks
