POR-15 Patch Filler and Seam Sealer

The ultimate filler adhesive. Apply right over rust or bare metal.

Fix that seam or channel with POR-15 Patch. For years our customers have asked us for a thicker version of our world famous POR-15 Rust Preventive Coating, to use for filling seams or holes. Here it is! POR-15 Patch is quite literally POR-15 Rust Preventive Coating in a tube, and it dries as hard as a rock, remains flexible, and once dry is totally impervious to fuels and solvents. This rust hole filler is so tough it may actually add strength to weakened metal, and it won’t absorb moisture and swell like conventional body fillers. Try this rust repair patch yourself.
