Gun Gum paste is safe to use on your exhaust, once it’s hardened the seal is gas tight and solid. You should use gloves when applying it though and avoid contact with skin.
We advise that you check the detail of the warranty with the provider.
Gun Gum creates a permanent gas tight seal, repairing holes for the life of your exhaust.
You should use a spatula to apply Gun Gum, and make sure you wear gloves. You can apply it using your fingers if needed (this can sometimes help in hard to reach areas), but always wear gloves for this.
The Gun Gum Easy Fit Repair Bandage is specially developed to fit difficult to mend areas. It has an adjustable edge which you can seal with Gun Gum paste to ensure that any part of your exhaust can be permanently fixed.
