Brownells Oxpho-Blue Cold Blue Cream 4oz

Brownells Oxpho-Blue is a professional-grade cold blue cream designed for touch-up bluing and refinishing metal gun parts. Applied without heat, it penetrates deeply into the metal for a lasting, even blue-black finish. Ideal for spot repairs on scratches, worn areas, and new metal surfaces. The cream formula clings to vertical and irregular surfaces for controlled, mess-free application. Comes in a 4oz container.
