Gun Gum Exhaust repair Paste - 200g

I had a small leak in my exhaust, which would have failed the MOT. Instead of replacing the whole exhaust system, which would have cost me a few hundred quid, I mended the hole with this paste. After 3 months, the seal is still intact.

I used Gun Gum on my peugeot 307 which i had to get rid of due to other errors, Once set the gungum was tough and durable wetting the applied area again made no challenge for this. Was perfectly fine. Once i separated the back box it was tough to remove.

Followed the instructions for a small hole in the catalytic converter. Checked the repair after 24hours and the product wasn't completely solid but the hole was sealed - it took a few days to harden off

Gun Gum Exhaust repair Paste - 200gThe item mentioned was perfect for the job I had to do. I found it very flexible with the spreading applicator included. I would certainly purchase again.

does what it's supposed to, easy to apply, clean area before applying with wire brush or sand paper for a good bond, i apply with my fingers with gloves on, seals small holes and leaks but don't expect it to fill in half a rotten exhaust

Took forever to harden.

Useful for a temporary repair. Once the exhaust starts to blow, a replacement is invariably needed.

Works but obviously a temporary fix.
