Abstract
General Axial Gauges within a perturbative approach to QCD are plagued by ' spurious' propagator singularities. Their regularisation has to face major conceptual and technical problems. We show that this obstacle is naturally absent within a Wilsonian or 'Exact' Renormalisation Group approach and exp lain why this is so. The axial gauge turns out to be a fixed point under th e flow, and the universal 1-loop running of the gauge coupling is computed.
