Used it to fill in rusted out gap on an oxygen sensor bung that was leaking air into the 02 sensor and causing false reading. So far so good I drove it 3 days no check engine light and the exhaust putty is holding up so far.
I have an older airtight woodstove and there were small cracks near the corners of the door cause by past over firing. I followed the directions to a T: grinding the cracks in the steel in a V formation and drilling out the end of the crack to keep them from getting longer, then cleaning the cracks out with electrical contact cleaner and troweling in the mixture with a small putty knife making sure to push the mixture well into the cracks. So far it has held up marvelously and I've burned a couple of very hot fires in the old woodstove. If all goes well, the repairs should last for many heating seasons. If they don't I'll be sure to report back on my results and update this review.
I used this to seal up the exhaust on my riding mower where the header pipe goes into the muffler.
Let's Go Blues!
I used this on a couple small holes in a 4 wheeler muffler. I have run it at full throttle with a very hot exhaust. All is holding tight.
After 24+ hours the filler had hardened and I sanded it down flat. Tested overnight with water, no leaks. Cleaned skillet thoroughly and went through two seasoning cycles @ 500 degrees for 1 hour plus cool down time. I have used the skillet a few times since and the repair has held up.
Received product today. Will update this after product has setup and been tested. It is easy to apply after you thoroughly clean and prep the surface. I have replaced this manifold 3 times and an tired of changing it. I wanted to try this method and see how long it lasts. I will let it cure at least 24 hours before starting my 06 Expedition. Once you mix the product you must use it all or throw it away.
This stuff works. Kept me from having to buy a new exhaust manifold.
