Impressed
400+ miles after using - no check engine light. We’ll see how long it lasts but definitely impressed so far.

Does what is says
I needed to plug up a leak on my cast iron exhaust manifold. Appeared that the manifold was warped. Used this to raised the low side and then used a flat plate to grind it down. Seems to hold up well so far.
