Using Holts Gun Gum to repair your exhaust is quick and easy. Follow the steps below to get the job done:

  1. Jack up the car to safely access the exhaust – you’ll need a jack or lifting kit to access your car’s undercarriage, and we’d also recommend a vehicle creeper to make getting in and out easier.
  2. Locate and inspect the damaged area – find the hole or crack and inspect it. How big is it? Where is it? And what is the area around it like? If it’s too big, in an awkward place, or there’s severe rust and corrosion around the area, you might need to take your car to a professional. If not, and the hole or crack looks repairable, you can continue to the next step.
  3. Choose the right Gun Gum accessory – for the Gun Gum system to work, you need the right repair accessory. There are four different solutions to choose from depending on where the hole or crack is, so make sure you get the one that corresponds best to your problem area. And remember, you also need a tub of Gun Gum Paste, which helps the repair accessory bond to the exhaust.
  4. Clean around the hole and remove loose dirt and rust – the Gun Gum Paste needs a clean, debris-free surface to stick to and ensure a gas-tight seal.
  5. Apply the Gun Gum Paste – using the spatula provided, apply half the Gun Gum Paste to the area around the hole or crack.
  6. Fit the bandage accessory – fit the bandage around the affected area, ensuring that the hole or crack is at the centre. Fix into place using the flat-head screw fitted to the bandage.
  7. Apply more Gun Gum Paste – seal the edges of the repair bandage with the remaining Gun Gum Paste, ensuring that all exposed edges are covered.
  8. Leave overnight to harden or run the engine slowly to speed up drying time – you need to leave the Paste to harden before you continue using your car. Avoid racing the engine, as this could hamper the drying process.
