I saw somebody try this on youtube. They sealed the cracks of their roaring exhaust manifold on an old ford expedition. They also applied this product over the fiberglass wrap, which I did not do. I would of done the same if my boyfriend didn't have to stress his 2 cents of it possibly overheating the manifold. (We're not mechanics)I give this product 4 stars, due to the fact it held the pressure of a 1991 international 5.9l school bus. From Orlando to Houston without the fiberglass, it held together. On the way back, it dried up and crumpled the same way JB weld does on an exhaust manifold.I would try this product again in the future. Good luck humans.
