Review: Great for exhaust systems. - I used this for dressing a new gasket connecting exhaust manifold to downpipe. Applied both sides of gasket. Very old car (44 years!) so outlet manifold was a bit scruffy and far from flat faced. This product helped the gasket produce a perfect seal. You don’t disconnect exhaust gaskets very often so it makes sense to do a good job sealing them back up when you do. This product helps a lot with that. Excels at applications involving hot exhaust joints, but not suitable for joints involving fuel.
Review: Replaced oven door gasket - The gasket holding the glass in place had come away around one corner. After watching "Re-sealing oven door glass" video on YouTube, I bought this stuff. Was expecting delivery in 48 hours. Arrived next day! Dismantled the door, cleaned everything up and applied the instant gasket. Left it overnight with plenty of weight on top. Used a craft knife and some steel wool to remove the excess. Job done! And I've only used about 1/4 of the tube. I ran the oven all day on slowly increasing temperatures up to full blast, then down again. The gasket's expansion did bleed through a bit, so a final trim was needed. Other than that, this stuff has replaced the original gasket with something far better and more secure. Great product. Good price. Delivery time exceeded expectations!

## Questions & Answers

**Q: Will this stick / seal between two silicone surfaces?**
A: I would say this is the wrong product - you probably need a good quality silicon adhesive and would need to buff/ket the surfaces of the silicon surface to form a bond. This product is designed to form a gasket (usually under pressure) so is more about making the two surfaces water-tight or air-tight than actually sticking them together.

**Q: Would it fix a leaking diesel injector seal?**
A: It would not recommend it for the use of fixing a leaking diesel injector.

**Q: Is this 100% pure silicone or has any additives? The ingredients aren’t listed. Thanks**
A: Technically, no silicon is 100% silicon.
Silicon is engineered to serve different purposes.
The dye is red or black which will be a silicon based additive.
To endure extreme hot and cold will require chemical additives too.
To resist petroleum products such as petrol and oil while serving as a gasket requires chemical intervention too.
It’s an automotive silicon gasket sealer which can be used to replace old fashioned paper gaskets.
It works.

If you really want pure silicon...good luck.
“Pure silicon” is a myth.

**Q: Would it work using on a lawnmower carburetor**
A: Depends which part , usually if its carb to engine you can buy a rubber gasket or gasket paper with this lightly smeared on would work
