FIBERFIXHeat Wrap Hardens Like Steel - For Exhaust Pipes and High Temp Repairs, 2" (1 Roll), Sienna Brown, 38501, 2" x 70", 2" x 70"

For $20, I would definitely recommend this heat wrap as a good temporary fix! As you can see in my photos, my minivan had a rusted out area on the catalytic converter lead-in pipe, right where its flange attaches to the exhaust manifold (nearer to the engine). The flange was not completed detached, which gave the tape somewhere to grip onto on both sides of the rust hole. Wrapped around easily while lying under the vehicle, after following instructions exactly. It was a bit hard to wrap the foil tape around, because my gloved hands were still a bit wet (I guess I should've dried them off or taken the gloves off). The foil tape doesn't really do anything, but keep the heat tape secure while it cures. I then dried it for about 15 minutes with a heat gun and ran the car for an hour in near-freezing outside temperatures.For a week, it was as quiet as new, driving about 15 minutes daily, but then after going on the highway for a few minutes, it became noticeably louder. It was still super quiet compared to without the heat tape, but it became noticeably louder. I looked under the car and it was still firmly attached. I also noticed that steam would be coming from it after a drive. Not sure what that was?The kit is great, as it comes with almost everything you need. I say "almost", because in addition to disposable gloves for installation of the heat tape, they give you a tiny piece of sandpaper to clean off the rust... you definitely should use a big wire brush to prep your area before application! Get as much rust off as you can before applying.Update: Lasted for over a year... I sold the car I put it on, but it was still holding up.

Well I have read other reviews of this product and wasn't sure what to expect, however it's been a week now since I used this product on my girlfriend's 1998 Subaru and so far so good. The exhaust pipe was completely broken into and it sounded like a rocket ship coming. But after I followed the instructions and wrapped the product around the broken pipe and no more rocket ship sound.lol Can't complain its working so far.. Not sure if it will last but the car sounds great now... Only took about 10 or 15 minutes of actual application of both the tapes although the reflective tape didn't seem to do anything. I wet the roll of tape, squeezed out the water and quickly crawled under the car to apply the tape. Make sure that you start wrapping about 3 inches before the break and continue wrapping past the break about 3 inches and pull the tape tightly as you are wrapping it around the pipe and after you finish wrapping squeeze the tape on the pipe for a couple of minutes. I personally let it sit for about an hour before I started the car and then I let the car run for about an hour to cure the tape and viola no more broken exhaust pipe... Hope it lasts and good luck to you.

Bom produto!

This stuff is amazing. They warn you and it is true, it cures in literally a minute, so be prepared, and be fast. I had to use pliers to get the last inch off the roll and apply it cos it cured so quickly. Good tip: the warmer the water the quicker it cures!I used it on an exhaust and while it says it can be used for that, it doesn't last long, maybe a few days at best, but in those few days it is excellent and does not leak. I highly doubt it is strong enough to be used to join a spade handle as they say, but it is fairly strong and makes a good seal for a temporary repair.
