Metal Protector® MD Quart


Metal Protector MD Installs an invisible, protective shield without altering the appearance of the metal.

Category: SKU: MPMD-1QT



This product formulation contains high-performance silicone designed to install durable, long-lasting protection to a variety of metal surfaces, including anodized aluminum, which is commonly found on window mullions. 

This product shields metal surfaces from water and oxygen, and helps prevent these elements from aiding in corrosion of the metal; thus preventing the need for frequent restoration. A barrier is created between contamination found in the environment and the metal surface, forcing stain-forming contaminants to settle on the polymeric coating.  These contaminates are then easily cleaned during regular window cleaning maintenance services.
This coating will last up to ten years depending on individual environmental conditions and the frequency of maintenance services performed on the substrate.

For best adhesion and protection, first restore surface with Metal ReSurfacer®. If contaminants are not removed prior to use, the adhesion ability of Metal Protector may be compromised. If applying this product after restoring the surface with EnviRestore Metal Stain Remover, use a solvent wipe to prepare the surface. Protect unintended surfaces. Always test in a small, inconspicuous area prior to application.


For invisible protection using Metal Protector MD: Apply product to metal surfaces with a sponge or rag. Spread Metal Protector in a circular, overlapping motion making sure to thoroughly work the product into every inch of the metal with multiple strokes. Once the area has been completely covered, use an absorbent rag or towel to remove excess residue and dry surface. For superior, yet invisible protection, apply product to surface creating an evenly wet coating and allow product to dry. Do not disturb the surface for 24 hours. Any wet rags that are laden with product may be flammable. special precautions should be taken to protect these items from exposure to any ignition sources.


In most circumstances, protected metal surfaces can be cleaned using only deionized water.
