Review: This stuff works great! - The bottom of my oven developed a couple of small holes from crinkling from thermal shock, so it was not holding its temperature very well. But this sealed up the holes easily and my oven holds its temperature once again! I originally bought this a couple of years ago and simply reapply it every six months. It lasts a long time! As for someone mentioning that its food safety is questionable because they only saw it on a sheet of paper, it has the NSF logo right on the bottle.
Review: Peace of mind - Used for a bbq pit. Workes like a charm

*by R***L on September 28, 2025*

Used for a bbq pit. Workes like a charm

### ⭐⭐⭐⭐⭐ Used this to seal an exhaust leak
*by C***N on August 2, 2023*

This is a really neat product and works perfectly to seal exhaust leaks on your car. Highly recommend even with the higher price. After tons of research this was the right choice and has held firm with its sealing and high temperature working ability. Use gloves, this will get on anything and everything and stain it permanently.
