## Description

J-B Weld is The Original Cold Weld two-part epoxy system that provides strong, lasting repairs to metal and multiple surfaces. Mixed at a ratio of 1:1, it forms a permanent bond and can be shaped, tapped, filed, sanded and drilled after curing. At room temperature, J-B Weld sets in 4-6 hours to a dark grey color. A full cure is reached in 15-24 hours. J-B Weld has a tensile strength of 5020 PSI and sets to a hard bond overnight. It can withstand temperatures up to 550ºF when fully cured.

Review: J-b weld - Title: Strong, Reliable, and Easy to Use Cold-Weld Epoxy for Permanent Repairs I’ve used the J-B Weld 8265S Steel Reinforced Epoxy for several home and automotive repairs, and it has consistently delivered strong, permanent bonds. The two-part formula (resin and hardener) mixes easily in a 1:1 ratio and sets within 4–6 hours, with a full cure in 15–24 hours. Once cured, it’s rock solid and can be drilled, sanded, or painted. I’ve successfully used it on metal, plastic, and even ceramic surfaces with excellent results. The bond strength is impressive—rated up to 3960 psi—and it holds up well to high temperatures (up to 550°F/288°C), which makes it suitable for engine components and exhaust repairs. What I like: • High tensile strength • Excellent heat resistance • Multi-surface adhesion • Easy to use, no special tools needed
Review: As expected - It is exactly what it is suppose to be: Smaller sized tubes of JB Weld. Convenient size for casual use. As far as the product... It is JB Weld It hardens like steel and is everything it claims it to be. I love it. It is an awesome 2-part epoxy that I have used on a few projects. Sands well and does what it needs to due. Dries to a grey color. Just give it enough time to cure real well and you'll be more than happy with it.

## Questions & Answers

**Q: Is this product electrically conductive?**
A: No. I saw a video on youtube where a guy made a cylinder head out of jb weld, and it did not ground the spark plug.

**Q: block crack between cyls 5 & 7 against the head, at the narrowest point between cyls. both cyls are sleeved. will jb hold the temp without breaking do**
A: thanks gpower. was looking online at the temp ratings of different epoxy products, actually found one @2100F, but with low tensile strength. I would like to stay away from welding as the crack is five eights long and sleeved at each end. just now pressure testing and the waterjacket has held 30 lbs for 12 hrs. I may also entertain some of the hi-tech block sealers, if it continues to hold pressure. thanks again for your input, and wish me luck putting life back in this old hemi. Dean

**Q: I have a number of small leaks in an older aluminum boat-- would JB work for a repair on this as a weld/filler for small punctures? thanks**
A: This is a general purpose epoxy that worked great for me on cast iron.  It does say you can use it for marine purposes, however you might also consider their product made specifically for water:http://www.amazon.com/J-B-Weld-8277-Water/dp/B000BRQ0TW/ref=sr_1_5?ie=UTF8&qid=1392730373&sr=8-5&keywords=jb+weldor look into the Permatex product made specifically for metalshttp://www.amazon.com/Permatex-84109-PermaPoxy-Minute-Multi-Metal/dp/B000ALDXV2/ref=sr_1_1?ie=UTF8&qid=1392730252&sr=8-1&keywords=metal+epoxy

**Q: Will this stop an exhaust leak right where a donut goes flanges off of the manifold?  Or which jb weld would work**
A: If your donut is bad you need to replace the donut. JBweld is a metal epoxy, you'll end up creating a permsnent bond wherever you've stuck it to and make it difficult to make a proper repair later without grinding it off.   If it's a crack you need to fix, spread it on thick and press in some wire mesh.. Fiberglass style patch. Let if cure and it should be good. Patched some long cracks that way. Hope that helps
