Review on Permatex Muffler Tailpipe Sealer 3 Pack by Rick Everett

My car's exhaust system had a small hole in the flange seam. Of course the hole was on the muffler side and I would have had to replace a perfectly good muffler for a few hundred bucks. Viewed this product and read recommendations from other users. Tried it for the lowest price. I sealed the hole and followed the curing instructions. I took the car on a long journey, drove it on bumps and rough roads. The outside temperature was about 30 degrees and the next morning the night was frozen. Driven 100 km home and checked. It was strong and didn't break or splinter. If there is a small defect, it works great.
