Description
Overview:
Holts Gun Gum Exhaust System Repair Paste is a high‐temperature sealing compound supplied in a 200 g tub for quick, reliable exhaust repairs. The grey, silicate‐based paste adheres to common exhaust materials such as mild steel and stainless steel, then cures with heat to form a hard, gas‐tight seal. It is suitable for cars, vans and motorcycles, as well as small plant and garden machinery with conventional exhausts, including generators and ride‐on mowers. Use it to seal joints, flanges, and small holes or cracks in silencers, tailpipes and downpipes to stop exhaust blow and restore performance. Easy to apply straight from the tub, it is ideal for workshop and roadside fixes. Identified by MPN 865 671 for straightforward reordering.
Key Features:
- High‐temperature formulation designed for exhaust environments, resisting heat and road conditions
- Creates a durable, gas‐tight seal for long‐lasting, permanent repairs when applied correctly
- Silicate‐based paste that cures with engine heat; no mixing required
- Bonds to clean steel exhaust surfaces, including pipes, boxes, joints and flanges
- Simple, clean application by spatula or gloved hand; excess can be smoothed before curing
- Effective on minor cracks, pinholes, seam leaks and slip‐joint connections
- Helps reduce exhaust noise and restore system integrity and back‐pressure
- Suitable for use alone or alongside an exhaust clamp or bandage for larger areas
- 200 g tub provides ample quantity for multiple small repairs or one larger patch
- Reliable in wet, salty UK road conditions and vibration typical of daily use
Typical Applications:

Useful for interim or permanent workshop fixes on passenger vehicles, light commercials, motorcycles, generators and mower exhausts. Apply to clean, de‐rusted metal and heat‐cycle the system to cure.
