Holts Gun Gum Exhaust Paste, Exhaust Repair Paste, Professional Quality Exhaust Sealant Paste To Create Gas Tight Seal & Stop Leaks, Reliable & Easy To Use For Fast Permanent Exhaust Repair, 200g

Used a few times to patch a blowing exhaust for the MOT (was the resonator this time). Works great, and as they say, there's nothing more permanent than a temporary repair.Pro-tip: Don't use the spatula if possible. Get a good pair of nitrile gloves and apply using your fingers then use the palm of your hand to smooth the finish.

This is great stuff, I was driving along the other day and seemed to have a crack on my catalytic converter, I wrapped some of this gum gum. Comes with a little plastic spreaderStarted the car and left it running for 10mins and noticed it straight away without a exhaust leak!Recommended and price is very reasonable. Also wear gloves when using the product ☺️

Not bad, especially given the low price. I used it to join the two halves of my Z750 exhaust after the connecting pipe sheered off. On its own I don't think it would have worked but used in conjection with some exhaust repair past and high temp fibreglass tape it seems to have made a solid repair. Hopefully will last long enough to source a replacement set of down pipes. In my opinion the tape and repair paste are essential. When I first fitted it there was quite a bit of movement and I was really not convinecd that it would work. After running the engine for 10 minutes the past has become rock hard and the join now feels very secure.If you buy this I think you will need some additional u clamps to secure it properly.

Does exactly what it's supposed to

Ok it did the job perfect but it was hard to put on had to use my hands to get it where i wanted it. .then it went off set like concrete and sealed the joint that was leaking. So well pleased with it

This done the job and sealed and hardened over time. But, because its a tube the paste inside separates into liquid and lumpy paste which you cant remix inside tube (better of with a tin). I had to squeeze most of it out and mix it which wasted the rest of the tube.

A good piece of kit for a solid repair. However, if your exhaust is corroded, it is only a temporary repair. I had already used the exhaust putty in several places which had lasted well and the bandage repaired a bigger hole. Within a few weeks, my exhaust fell off due to corrosion in other areas

Does the job tl twmp fix a exhust leak
