A high-temperature sealant for exhaust system repair. It often happens that due to constant condensation in the exhaust system, the car's muffler eventually rots. One small hole in the exhaust and the car starts to sound unpleasant. If the hole is not too big yet - it can be repaired with a sealant. This sealant can withstand heat up to 2000 degrees Fahrenheit, so it can be safely used in such units as the exhaust. You need to degrease the surface, then wet it with water, and then simply apply the sealant to the damaged area. After 30 minutes, the sealant will fully cure.
