We ordered this high heat-resistant cement Visbella from AliExpress for 5 euros.
But be careful, to don't do the mistake we did.
Don't put a lot of it because it will make a bubble in the end after heating, and it has a possibility to make a whole.
Watch this video to learn how to use this exhaust system heat-resistant Cement Visbella.
It can resist temperatures until 2012 Fahrenheit (1,100 °C).
It is also Iron reinforced.
Again don't do this mistake it can be okay at first but then after heating there will be a bubble, and it will make a hole in the end.
Now it's time to try to heat it after 1 day of the cement drying.
First we painted the grill and the burner with heat-resistant black paint, and then we heated it and here you can see the bubble getting bigger.
