I reckon that's nurrish's secret batcave....
Make sure you end up painting the whole wheel rather than just the faces, and I do mean taking off the tyres and spraying them complete.
Reason is that it makes a complete coat and reduces the chances of peeling, flaking or bubbeling, because there is no edge for for anything to get under.
My bro has a set of PVM wheels for his CBR600, which are powdercoated black, but on one of the edges (the surface that faces the hub when mounting) had chipped a little, but the knock on effect was that the powder coat damage got more and more. Harris UK thankfully replaced the wheels with a new set free of charge, because the manager took a look at them and instantly said that the powdercoat looked off. PVMs are made to order and hence the £1000 pricetag per pair.
But other than that, it's looking good.
