The Powermaster alternator that was supplied with the kit came to us polished. Since we're really not into bling, we blew it apart and had the casing powdercoated in a satin black that almost perfectly matches the system's anodizing. Total cost was $40 to have alternator rebuilt and $20 for the powdercoating. Well worth it in our opinion. You can also see where we installed the three stand-off sleeves.
