I've done about 10 sets of wheels in this finish. The product is made by PPG. It's called 'Chrome Shadow' and the part number is: 452-86973.
You start by priming and painting the wheels in 2K Direct Gloss. I reduce it 3:1:1 and you have to use Fast hardener. I also generally use fast reducer as well unless it's really hot. After you do you 2-3 coats, you need to low bake the wheels for 30 minutes @ 60 degrees celcius.
Within one hour of the bake process conculding, you then need to take a 1.0mm touch up gravity fed spray gun, and fill it with well stirred (did I say, well-stirred!) Chrome Shadow. You set the pressure at about 40psi at the regulator, and you then mist the Chrome Shadow on. The critical step here is to mist the coats on LIGHTLY! If you put it on too heavy, it will fry the 2K up to which there is absolutely NO recovery but to start from scratch (ie. new 2K). If you do fewer coats (approx. 3-4), you will get a black chrome finish, but if you put more coats on (about 7-8 coats),you get the Hyper Silver like in the pic.
You could do a matt or satin clearcoat, but I have only ever seen, and used a full gloss clear. After you spray your 2-3 coats of clear, you need to low bake the wheels again for the time prescribed by your clearcoat's TDS. You then need to wait a minimum of 1 week before attempting to fit tyres. You need to wait longer than normal because you have double the amount of product on the wheels.
I must stress how important booth and painter hygeine is when using this product. Because, if you get any dirt/crap in any part of the job, it will show up in the finished job. And you can't wetsand out the dirt/crap from the 2K or the Chrome Shadow. What you paint is what you get. I'm serious.
And, for you DIY'ers, because the Chrome Shadow product must be applied over baked but still fresh 2K, sorry, but you cannot apply this product if you don't have/use a low bake booth.
