This would be a pointless exercise because it will never happen. VOSA is only concerned with safety related recalls and does not issue them via the DVLA until after discussion with the manufacturer (a bit like plea bargaining in a court case). Your rusty iron ore hubs are entirely normal. Usually these are left unpainted because all that ever occurs to them is surface rust. They get too hot for rust to penetrate. They could be painted with Sperex VHT (very high temperature) paint and this is what some BMW dealers have done when customers complained.
