Applying gun gum paste is a straightforward process for repairing small holes and cracks in an exhaust system. The key steps involve preparing the surface, firmly applying the paste, moulding it into the damage, and allowing it to cure.
Essential Steps for Application
To effectively apply gun gum paste and ensure a durable seal, follow these steps:
1. Prepare the Surface
Before applying the paste, ensure the exhaust surface around the damaged area is clean, dry, and free from rust, grease, or loose debris. Using a wire brush or sandpaper can help achieve a clean bonding surface.
2. Apply the Paste Firmly
Take the gun gum paste and begin applying it directly to the hole or crack. Press the paste firmly into the hole or crack on the exhaust system, ensuring that it completely fills the damaged area. This firm pressure helps the paste bond securely and fill the void thoroughly.
3. Mould and Smooth
Once the paste is in place, use your fingers or a spatula to mould and smooth the paste as needed. Shape the paste so it covers the damaged area effectively and blends smoothly with the surrounding exhaust pipe. Ensure the coverage extends slightly beyond the edges of the damage.
4. Allow to Cure
After the Gun Gum Paste is applied, allow it to cure according to the manufacturer's instructions. Curing time can vary depending on the specific product and environmental conditions. Some pastes require the engine to be run for a short period, while others air dry over several hours. Always check the product packaging for the correct curing procedure and recommended duration.
Practical Tips for Best Results
- Surface Temperature: Ensure the exhaust system is cool before beginning the repair to avoid burns and to allow the paste to handle easily.
- Wear Gloves: Gun gum paste can be messy. Wearing protective gloves is recommended during application.
- Adequate Amount: Don't be shy with the paste. Use enough to completely fill the damage and create a solid repair.
- Following Instructions: Curing is critical for the paste to harden into a durable repair. Strictly follow the manufacturer's curing instructions.
By following these steps, you can effectively apply gun gum paste to seal leaks and extend the life of your exhaust system.
