EXO-GUM

Exo-gum (or exhaust gum) is an adhesive material used to seal small cracks, holes, or leaks in a vehicle’s exhaust system. 

It is typically a paste designed to withstand the high temperatures and vibrations generated by a car’s exhaust system. Once cured (often with heat from running the engine slowly), it forms a tough, gas-tight seal, offering a cost-effective alternative to replacing the entire exhaust component for minor damages. A well-known product of this type is “Holts Gun Gum,” which is also sold under the “EXO-GUM” brand in some regions, such as Kenya
