Permatex 50345 Metal Patch And Fill, Charcoal Gray, 3.5 Oz.

Permatex Metal Patch and Fill is a two-part epoxy compound designed to repair broken, rusted, or corroded metal surfaces on steel and aluminum. This high-performance filler builds up worn areas, seals gaps, and restores structural integrity without requiring expensive part replacement. Whether you're patching a gutter, grate, fence, ductwork, tank, or aluminum boat, this product delivers a durable, professional-grade repair that withstands harsh conditions.

The formulation is waterproof and resists oil, gasoline, and most chemicals, making it ideal for automotive, marine, and outdoor applications. Once fully cured, the hardened compound can be drilled for fasteners, sanded smooth, or painted to match surrounding surfaces, giving you complete control over the final finish.
