J-B Weld DS114 Perm-O-Seal Radiator Stop Leak Sealant, 0.07 Oz

J-B Weld Perm-O-Seal is a specially formulated non-toxic compound ground to a very fine particle size to quickly mix and flow into all areas of the cooling system to find and seal leaks. The powered concentrate allows for an economical repair as compared to liquid based alternatives that use similar technology. The special compound will quickly seal leaks and will also act as a rust inhibitor and lubricant to internal cooling system parts. It will not clog or harm your cooling system.

Highlights:

• Mixture of seven organic ingredients designed to permanently seal holes and cracks in radiators, water jackets, and cylinder heads
• Just pour into the radiator while the engine is running, it seeks out holes, and swells shut as soon as it comes in contact with air
• Will not re-dissolve, and draining or flushing will not affect the seal
• On a card
• Permanent repairs for all car, truck, van, bus and tractor radiators
• Will not clog or harm cooling system
• Pour contents of package slowly into radiator while running motor fast enough to circulate the water
• Continue to run motor until water is hot and leak stops
