Permatex80335 Muffler and Tailpipe Sealer, 3 oz., Plastic, 1 Count (Pack of 1)

Great stuff to use when sealing up an assembled exhaust kit for my f150. Easy to apply. Been on for 6 months with no leaks.

Works awesome just make sure you wet the place your gonna apply it to and put it on thick I let it sit for 1/2 hr then started my bike and let it run for 10 minutes no issues and no leak also if you have some left over make sure to put the cap on it will keep

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.

I searched for a long time before deciding on this product to provide an extra seal to my exhausts catalytic converter flange. The flange in front of the cat was leaking, and so I r&r'd the old bolts, and then I wire wheeled the mating surfaces. Despite this, there was still a decent bit of pitting, and this 'sealant' worked well to fill in any imperfections that were present. I did this roughly 6 months ago, and daily drive the vehicle - no leaks from the area that was patched. I even reused the old 'donut' gasket since I didn't want to spend any extra money or time on this repair. I would recommend this to anyone who is working on an older vehicle with a rusty exhaust, or to anyone who wants to exercise an abundance of caution when trying to prevent any exhaust leaks following a repair.

muy bueno,sella muy bien y endurece rapido.fuerte. lo utilice para sellar un hueco en el silenciador de mi dodge stratus.

This is decent for a temporary patch. Please don't expect this to hold up long term but for short term repairs this does the job. Over time it crumbles away.

Arrived quickly, well packaged

Whatever you do, don't get it on your skin. (The red stuff that is) I had to use mineral spirits to get it off (which I'm sure is a cancer risk in California. It's a good thing I don't live in California) Use a double layer of disposable gloves. Also, if you can't attach the flanges due to rusted bolt filled holes, go to harbor freight and buy the cheap mini vise grips, 1 for each side of the flanges. Lock 'em super tight and secure the handles with zip ties. (Our exhaust issue was that the muffler separated from the main pipe at the attachment flanges.UPDATE: I'm not positive that I reviewed the correct item. All I know is that it was red like the picture and really thick and sticky. A few weeks after this repair I sealed the top rear seam with a piece of a pop can, some steel window screen and the GRAY colored stuff, which comes off much more easily with soap and water. Sorry for the confusion.
