PIG™ Plug-N-Seal® No-Freeze Patching Paste

Absolutely fantastic. The Fire Company recently , 3-23-2021, responded to an overturned tractor trailer leaking fluids. Upon arrival it was UN 1203 gasoline, but actually was racing fuel spraying out at 4 locations. We dammed the runoff and took the PlugNSeal and applied to punctures in tanker. This product far surpassed our expectations and basically stopped the racing fuel from leaking. Three of the punctures were about one inch diameter but the largest was nearly 2 1/2 inch puncture with elongated tear in metal. With one large handful of this product, it was pushed into large puncture and spread out around the hole to provide surface area for bonding. Although the hope was to slow spillage of the fuel till HazMat team arrived,this product held for hours with little seepage from the largest puncture. Fuel was vacuumed out of that compartment of the trailer approximately 4 hours after it was applied and it was still holding.

Good for temporary patching products. We carry it on all our trucks for emergency repairs offsite to keep a small spill from turning into a major spill. The ant-freezing paste is best since we store them outside on the trucks.
