Permatex 80335 Muffler and Tailpipe Sealer, 3 oz.

Works very well

I recently purchased a product for my exhaust system, as there was some leakage around the joint. Despite following the instructions carefully, the paste came out within an hour of application. Additionally, after just two days, there's no sign of the product I previously applied. Based on my experience, I strongly advise "don't buy it"

It's dried up and unusable. Major scam

Perfect! Thanks so much, it is hard to find this. It arrived just as you said. Permatex is top quality.

かなり柔らかいパテです その分使いやすく、簡単に穴補修ができます 耐久性は分かりませんが、期待はしてないです

Great value

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!

I wish I had pictures of the patch my husband made on the tailpipe. He said it was super easy to use (easier than j.b. weld which he loves). I bought it about two yrs ago thinking it was only one and when I received it,(12 deep!) I laughed a bit and shrugged, the hubs chuckled and said we'd use it. We have and by "we" I mean "he" ... it made a huge difference on the above mentioned repair, it has lasted over a year now, no joke, what was supposed to be a temporary fix became semi-permanent! "What!?!? That can't be true" you might be saying but I'm here to set the record straight...it IS true! Long lasting, easy to use, obviously thick and stays where its placed, what more could one ask for...maybe a husband who is very handy.
