POR-15 rust preventive coating, to use for filling seams or holes. POR-15 Patch is quite literally POR-15 rust preventive coating in a tube, and once dry it remains flexible and is totally impervious to fuels and solvents. It's so tough it may actually add strength to weakened metal, and it won't absorb moisture and swell like conventional body fillers. Try it yourself, it's incredible! Patches holes or cracks in steel, wood, and some plastics.
