PT-522 Zinc Chromate is a general purpose, rust inhibitive, alkyd primer. It is intended for use over metals that are bare, scuffed, sanded, lightly rusted, abrasive blasted and previously painted surfaces while showing excellent anti corrosion properties. The primer chemically etches into the surface to provide exceptional adhesion and durability. Although this primer is intended for metals, it may be applied to wood, composite and concrete surfaces.
Also available in gallons.
