Review: Habe noch nicht probiert
Review: Vivo lejos de la ciudad y esperaba que esto funcionara. Hice todo de la manera correcta y lo dejé secar toda la noche…. pero cuando llevé mi Quad para probarlo, duró un día y toda la resina se partió en dos. Y ahora estoy de vuelta al punto de partida. Mi silenciador se rompió nuevamente y este producto fue una total pérdida de dinero. Estoy muy triste ahora.

## Questions & Answers

**Q: Is this black when cured?**
A: white

**Q: Can this work on low pressure AC ?**
A: I would not use a repair item on an AC line. Best to use new parts. Also may not be legal in your city/state because of the freon

**Q: Will this product hold securely to wrap around a car muffler?**
A: Not a chance. I haven't left a 1-star review, but this was horrible stuff. I'd previously ordered and applied another product which seemed to perform well: for a couple of weeks. And being an otherwise fan of J-B Weld products I gave this a go. It was both a PITA to use and lasted one drive. My muffler had a hole, though not from rust, but to sufficiently wrap this around a muffler and seal you need a good 4-5 kits (I wrapped 4). I ultimately had a weld patch done on the muffler—which I should have done from the start—but was sold on different DIY crap. This product may be fine for a pipe leak, but if you are looking to seal a muffler leak, don't. Cheaper to fix the muffler.

**Q: Will this work Cast iron water pipe underneath a clamp?**
A: do  not know- probably  by coating  some  fiberglass  fabric   wrapping it   and then  clamping. I would try it

I used JB Weld Exhaust Tape to repair a small leak in my exhaust pipe, and it worked perfectly! What I Liked: • Easy to Use: The application was straightforward—just wrap it around the damaged area, and the heat from the exhaust cures it quickly. • Durable: After driving for a week, the tape is holding up well, even under high heat and regular vibrations. • Cost-Effective: A budget-friendly solution to fix minor exhaust issues without the need for professional repairs. This tape saved me time and money, and I’d recommend it to anyone looking for a reliable temporary fix for small exhaust leaks!
