    Read the reviews, which I'm appreciative of. Tried first that bandage stuff, sucks but this stuff dries quick. I recommend using a latex glove to put it on. I had a ton of holes and cracks, used 3 tubes and now I'm good as new.

    Good temporary fix

    Good for a temporary fix to small leaks but not a good permanant repair. Heat and pressure will eventually cause product failure.

      Comments about Permatex Muffler & Tailpipe Sealer (3 oz):

      It works as described. I used one tube to fix an exhaust leak that failed inspection. Just wet the patch location and put this stuff on. Also, you want to wet your fingers too, which will make them less sticky to your fingers and easy to smooth out. Use a spray bottle to do so. After done, wait for 30 minutes, then run the car idle for 10-20 minutes, you are ready to go.
      Mine fix passed the infection. And nothing the inspection guy could do about it.

        Buy 2 tubes just in case!

        By Saturn Owner

        from Richmond, VA

        Comments about Permatex Muffler & Tailpipe Sealer (3 oz):

        I used this to seal the connection between a new muffler and tail pipe on a 1995 satrun sl. after cutting off the old muffler, i connected the new muffler to the exhaust pipe with a u-clamp. i failed to coat the outside of the pipe with the sealer before connecting muffer inlet pipe though. that was a mistake. but i was able to seal a condensation leak by LIBERALLY applying two tubes of sealer around the connection and over the u-clamp. don't worry about looks. just gob it on. inspection passsed!!!

          I had a cracked downpipe on my car and it sounded like garbage. I was skeptical about trying this product but the downpipe was expensive and it was too cold out to change it. The other reviews were good so i picked up a tube. I wore gloves like another reviewer suggested and smeared it on the crack. The next day i fired it up and its been holding up for a few months now.

              Wear rubber gloves cause it can be messy but other than that it creates a great seal and does the job.

              This paste works great at totally sealing an exhaust connection. Cures fast and stays pliable. Basically, this is a high temp silicon sealant.

              The wifes Bravada had a rotted out spot on top of muffler...cut me a piece of tin an little bigger than hole and gobbed a bunch of this product on the piece of tin I cut then put it over hole....grounded clean with a air tool wire brush of course then gobbed a bunch of this all around the seams of the patch, let dry for 3-4 hours and no more exhaust leak.

                    This is a good product to seal small gaps when installing new or used exhaust systems. Helps to seal that pesky leak without having to tighten the clamps to crushing capacity or welding the seams.
