Nice product.. even at 800°C.. still hanging on.
Im using this stuff to seal up the flanges of a homemade jet engine. High pressure, high temp, and corrosive environment.. it works great.

Flakes and doesn't adhere very well
It's ok. I'm using this to fill in the cracks in the seams of my fireproof file cabinet. This was a used file cabinet and the cracks formed while it was being moved. This sealant wasn't very sticky and tended to flake off when I tried to smooth in into the cracks. Basically, it did not do a good job of sealing the cracks. In hindsight, I probably would have been better off using standard caulk considering how small the cracks were.

Works great.
I used this to fill in the electrical hole and floor anchor holes. The product is as described. Seals great and eliminated air flow. Easy to apply and fills in very well. Don’t get this stuff where you don’t want it, can be difficult to clean. Once dryer the plastic caps in the safe were secured and don’t pop out. Extremely durable. Can be cut with a razor blade to add a nice finished look.

Dried up & Fell Off
I tried using this product to seal small seams in stainless steel inside a homemade smoker I built. It flowed out nicely & dried, then I turned up the heat in the unit to cure it (per directions), and after it cooled down, it all dried up, cracked and fell off. Now I'm scraping off what's left, vacuuming it out and looking for something that really will work. Needless to say, I'm not impressed. I see lots of other folks seem to have had good luck with the product, but I certainly didn't. I really don't know how a person can apply it incorrectly unless it was too cold outside when I applied it (upper 40's, lower 50's) but if that's the case, there should be warnings on the label advising against application in less-than-ideal conditions. And yes, the surfaces I applied it too were cleaned (wiped down with alcohol prior to application).
