Mix: Open J-B Weld® Extreme Heat™. Thoroughly mix the product.
Apply: Use product generously, working onto surface or into hole, crack, pit or seam. Repeat as needed. Allow 2-4 hours set up, depending on temperature and current environment.
Dry: Test cure by pressing fingernail or thumbnail into repair material. If unable to penetrate, then repair is complete. If area appears slightly soft, use a non-flame heat source, such as a hair dryer, to speed cure time, or allow 24 hours before allowing high heat exposure. Repeat test until fully cured.

Great for repairing Silencers

My friend's car started releasing obnoxious gas inside the cabin. A check revealed that there was a hole in the exhaust just after the manifold.
A FNG asked for about Rs.3000/- to fix. I suggested to my friend that try this JB Weld Extreme Heat. We ordered through this site.
We added layer after layer to the exhaust pipe. It was nearly the size of the old 25 Pisa coin. Luckily for us, it was visible and so we didn't have to dismantle anything. We waited for one full day before we started the engine. Hey Presto ! No more leak. It has been a month since we patched it.
Did I tell you JB Extreme Heat is cheaper in this site than any other sites online ?
