£40-£50 is a normal kind of price for simply blasting and powder-coating (depending on the colour). The additional price for repairing the kerbing all depends on how bad it is. If it's not that bad, it could be something you simply blend back in yourself with a file and wet and dry.
Bronze.. delicious, its the colour I want but I just cant justify spending money on wheels when I'm saving for a house at the mo
Would like to see how it turns out though!
