We study renormalization of Coulomb-gauge QCD within the Lagrangian, second-order, formalism. We derive a Ward identity and the Zinn-Justin equation, and, with the help of the latter, we give a proof of algebraic renormalizability of the theory. Through diagrammatic analysis, we show that, in the strict Coulomb gauge, ${g}^{2}{D}^{00}$ is invariant under renormalization. (${D}^{00}$ is the time-time component of the gluon propagator.)
