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 wont absorb moisture and swell like conventional body fillers. Try this rust repair patch yourself. This sandable seam sealer is incredible! This rust hole repair product also patches holes or cracks in steel wood and some plastics.
