Birchwood Casey Perma Blue Cold Blue Paste 2 oz

Birchwood Casey Perma Blue Cold Blue is a paste-form cold blueing compound used to touch up worn or scratched areas and re-blue clean, rust-free metal surfaces on firearms. It is applied at room temperature, so no heat is required.

The paste reacts more slowly than liquid blue formulas, which the manufacturer notes gives it longer-lasting results. It can be applied with swabs such as cotton-tipped applicators. Birchwood Casey recommends cleaning the metal first with its Cleaner-Degreaser before application.

This product is a 2 oz container of blue-finish paste intended for firearm metal surfaces.
