Holts Gun Gum is one of the easiest and most effective ways to fix small holes and cracks. This specialist exhaust repair system provides a permanent, gas-tight seal for holes and cracks along the entire length of the exhaust assembly, so you don’t need to replace any parts or components.

Using Holts Gun Gum is simple, and the job can be done at home by DIYers who can safely access their car’s undercarriage (with a jack or car lifting kit). You’ll need a tub of Holts Gun Gum Paste and the right Gun Gum bandage to perform the repair – more on this later.
