Permatex 80335 Muffler and Tailpipe Sealer, 3 oz.

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.

Great value

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.

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.

No cumple con la función de ser pegado y como vi algunos vídeos de YouTube decían que era bastante bueno pero como dicen en un vídeo y dicen en las instrucciones el sitio donde va la pasta tene que estar limpio pones está bastante limpio le pase un cepillo de púas de acero y luego puse agua y luego la pasta lo dejé secar 24h y luego puse en marcha el motor y en el escape se salió denuevo el agujero y un agujero pequeño aparte se hace como pompa parece chicle no lo recomiendo aparte no es soldadura en frío y no alcanza 2000 grados sino alcanza 110 grados y ya no sirve no lo recomiendo
