POR-15 Patch Tube Sealer Rust tank Repair

POR-15 Patch, 4oz tube.  For years, POR-15 customers have asked for a thicker version of their world-famous POR-15 for filling in seams or holes. Here it is! POR Patch is, quite literally, POR-15 in a tube. Like POR-15, it dries as hard as a rock, remains flexible, and once dry, is totally impervious to fuels and solvents. It's so tough that it actually adds strength to weakened metal and it won't absorb moisture and swell like conventional body fillers. Try it yourself--it's incredible!
