### ⭐⭐⭐⭐⭐ Works great

### ⭐⭐⭐⭐ Has a limited shelf life but works well
*by M***3 on July 10, 2024*

The product itself is awesome. Seems anything I buy from Permatex does what it is supposed to do. For this particular "repair" I was a bit unsure as to which Permatex product to purchase. My motorcycle exhaust has a connection where the header pipe and tailpipe meet. An aftermarket "Jardine" exhaust and oddly quite a large gap at the connection whereas the bracket is supposed to crimp and does not do a very good job at sealing it. This may be how it was designed but for me an exhaust leak in your plan is not a good plan. Bottom line i wanted to seal this joint but wanted the option to take it apart to install new header gaskets down the line. Reaching out to Permatex they actually recommended a different product that was twice the cost of this with half the temp limit. I am happy I chose this as it sealed the joint and I was able to disconnect the pipes and install the gaskets. I am now looking to try a "lap joint" bracket as I would prefer a more permanent solution. I feel anything with the Permatex name is a good product but has limited shelf life and will eventually break down. The trouble is they make so many similar products it is hard to choose the correct one. In my opinion there is not one single best application for a particular project. Doing some research prior to buying is always recommended.
