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.

Does the job but very messy

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.

Great temporary fix for a small leak which has become more of a permanent fix. Easy to use and very pliable which makes it easier to apply. TIP wear glasses or goggles if applying whilst under vehicle 👍

No problems with this seller. Item as described

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.
