Your Exhaust Putty FAQs Answered

The Holts Gun Gum range is trusted by professionals and DIYers alike as one of the best exhaust repair systems on the market. If you’re looking for advice on how to get the best results when using Holts Gun Gum Exhaust Paste, our FAQs provide some useful tips and insights.

What is exhaust putty?

Holts Gun Gum Exhaust Paste is a repair putty that provides a flexible, permanent way to repair a car exhaust. Used with the Gun Gum Exhaust Repair system, the putty adheres to both the exhaust material and the repair bandage, forming a gas-tight seal that hardens as it dries to provide a durable, permanent repair.

Gun Gum Paste has been extensively tested in the lab and on the road to ensure it works in all conditions. Heat and moisture resistant, the putty makes it easy to fix small holes and cracks on an exhaust system without the need for an expensive full repair or replacement parts.

How do I use exhaust putty?

Using Holts Exhaust Repair Paste is easy. The tub comes with an application spatula to make it easy to apply the putty exactly where you need it.

Ready to use right out of the tub; apply half of the Gun Gum Paste to the area you want to repair, before attaching a suitable Gun Gum Repair Bandage. When the bandage is in place, apply the rest of the putty over the entire area, particularly over the joins where the bandage meets the exhaust.

Drying times vary depending on the conditions, but you can also run the engine to help speed up the time it takes for the putty to harden. Once it’s dry, you’ll have a solid, permanent repair that guarantees no leaks.

Is exhaust putty safe to use?
