  Recently a new type of quadratic gauge was introduced in QCD in which the
degrees of freedom are suggestive of a phase of abelian dominance. In its
simplest form it is also free of Gribov ambiguity. However this gauge is not
suitable for usual perturbation theory. The finite field dependent BRST
(FFBRST) transformation is a method established to interrelate generating
functionals for different effective versions of gauge fixed field theories. In
this paper we propose a FFBRST transformation suitable for transforming the
theory in the new quadratic gauge into the standard Lorenz gauge Faddeev-Popov
version of the effective lagrangian. The task is made interesting by the fact
the BRST invariance obeyed by the two effective lagrangians are not the same,
however suitable extension of the previous procedures accomplishes the required
result. We are thus able to identify a field redefinition to go from a
non-perturbative phase of QCD to perturbative QCD.
