Review: Great stuff - I rebuilt a portion of my exhaust and I had two flanges that didn't meet together like they should which left a small gap at the bottom. It wasn't bad enough to cause an audible exhaust leak, but condensation would leak from it. I figured some exhaust sealant would be a quick fix as opposed to resetting and re-welding the flanges back on. I was a bit dismayed when I received the product and realized it's not epoxy or solvent based, so I wasn't sure how effective it would be. I went ahead and tried it following the directions and it worked absolutely fantastic. It goes on fairly smoothly-- sort of comes out in globs, but it's easy enough to work into a nice bead. Evidently it's made from some sort of clay, but it worked like magic and hardens almost like a super smooth cement. I don't see it coming off anytime soon. Instructions go something like this: wet the area apply the product wait 30 minutes start engine and let run for 10 minutes. After that engine running period it's pretty well cured by that point, but I'm certain within a couple hours you're good to go. I would definitely buy it again.
Review: Great stuff for repair - Stuff worked great for my application. I had about an 1/4” x 1.5” crack/ rusted out area in my exhaust pipe. It in right next to where piece of heat shielding attached so it was easier to fill, but it would of worked if it was just a 1/4 crack anywhere. Applied as directed and worked great, amazing in fact. It’s only been a week, so idk how long it will hold. The pictures show prior, right after application and fully cured. It smooths out nice too. Still for a lot left in the tube. UPDATE MARCH2020: so after about a year this stuff fell off, but I think it was due to some other variables. Still, for a patch to hold a year is great! I just applied more today, the hole is still the same size too so It’s good it didn’t get worse. My muffler has a lot of surface rust, but this is the only hole and it still seems solid- so if I keep patching this every year, for 6$ and about 5 min of work, I can’t complain! Truthfully it lasted longer then I expected. Probably enough left in the tube for maybe one more application (3 total applications, but I put a lot on). It still get 5 stars!

### ⭐⭐⭐⭐ 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.
