E6000 vs. JB Weld: what’s the difference?
E6000 has higher flexibility and elongation but lower strength compared to JB Weld. E6000 can bond with a wider variety of materials but has lower chemical resistance. JB Weld forms a harder bond and can withstand higher temperatures. E6000 cures faster and is more user-friendly as a versatile household glue.
E6000 vs. JB Weld: Specs & Uses
⏰Cure Time
E6000: 24-72 hours
JB Weld: 4-6 hours
💲Price
E6000: Low, around $5 per tube

🛠️Common Uses
E6000 can be used to glue fake fireplace logs in a gas fireplace heater; glue cork tiles to an aluminum patio ceiling; bond patches, attach embellishments, or repair torn seams; can fill small gaps, allowing for a strong bond even in uneven surfaces
JB Weld can be used to block cracks between engine cylinders; repair small punctures and leaks in older aluminum boats; patch exhaust leaks, especially at the point where a donut goes flanges off the manifold

My Hands-on Test of E6000
✅Cures Well Even in Humid Conditions
It is easy to work with and cures well even in humid conditions. The bond created between dissimilar materials, like a metal hoop and a stone pendant, is strong and durable.
In terms of materials it can bond, E6000 is incredibly versatile. I’ve used it to adhere rubber thresholds to painted concrete floors with great success. It creates an extremely strong and permanent bond. For adhering delicate items like feathers, I find it’s best to apply just a thin line of the thick adhesive to the spine rather than trying to spread it.
The set time is fairly quick – it will be quite tacky in just a minute or so. However, I always leave whatever I’m gluing undisturbed overnight to allow for a full, rock-solid cure. With that said, I have used it for quick repairs in a pinch, like re-gluing shoe soles, by holding the pieces tightly together with tape or weights until its initial set.
E6000 forms an incredibly strong bond on so many materials – rubber, glass, tile, leather, wood, metal, and more. I’ve used it to attach tiles to wood surfaces by applying a generous amount and clamping the pieces together until cured. For gluing a faux leather belt back together, you just have to be very precise with application and Go sparingly, as the adhesive can soak through.
I’ve even used E6000 to write names on Christmas stockings and then applied glitter over the raised adhesive letters for a cool sparkly effect that was completely permanent. Just be cautious using it for decorative purposes as it does have a strong chemical odor until fully cured.
❌Downsides
For repairs like re-attaching a heavy side mirror housing on a car, E6000 should have the strength, but getting the proper alignment and pressure while it sets could be tricky. There are likely better auto-specific adhesives for that application. I wouldn’t recommend it for auto glass either.
What is the Best Glue for Hard Plastics?
One downside is that E6000 can be really difficult to remove if it drips or oozes out. You’ll need something like Goo Gone or mineral spirits to clean up any mistakes. It’s also not recommended for use on very delicate materials like thin polyester garments where you’d want a dedicated fabric glue or adhesive.
FAQ of E6000
Q: Would E6000 work to glue foam to a plastic lid of a Pelican case?
A: Yes, this glue can be used to attach the foam to plastic, but it’s recommended to scour the plastic surface with 220 grit first and make sure it’s clean with acetone or 90% alcohol.
Q: What is the maximum temperature that this adhesive can withstand for a ceramic plate setter in a grill/smoker?
A: It’s unlikely that this glue is designed to withstand such high temperatures.
Q: Is E6000 resistant to gasoline and does it harden?
A: It’s uncertain if this glue is resistant to gasoline, but constant exposure to gasoline may erode the bond. The glue remains somewhat flexible when it dries. However, I’ve listed the plastic epoxy for gas tank repair that should be resistant to gasoline, feel free to read it.

My Hands-on Test of JB Weld
✅Pros
What I love most about JB Weld is its versatility. It works wonders on many different materials, and it’s much better than other adhesives like crazy glue or gorilla glue. I highly recommend allowing the recommended 24-hour wait time for the adhesive to fully cure for the best results.
While using JB Weld, I did notice that the recommended 1:1 or 50/50 ratio of hardener to adhesive left the results slightly sticky. However, I found that using a 40/60 ratio of more hardener still gave me plenty of time to work with and finished without any stickiness.
It’s easy to apply and comes with easy-to-follow instructions. I used it to repair the aluminum casting on my lawnmower that holds the carburetor on, and it’s now solid as a rock.
One of my favorite things about JB Weld Original is how well it holds under pressure in most conditions. I have used it to patch small holes in metal and to fix a set of high-end Italian-made stainless steel cookware that I’ve had for 30 years. The handle on one of the pot lids snapped off at the spot weld connections, but JB Weld Original saved the day. I highly recommend this product for applications needing high storage and heat resistance.
Overall, I am thoroughly impressed with JB Weld and highly recommend it to anyone looking for a reliable adhesive. It’s the best stuff for metal-to-metal adhesion and can even be used to weld broken metal items. It sets up fast and dries to a truly steel-like hardness. I’m glad I found this product and will continue to use it for all my DIY projects.
Is JB Weld Conductive?
No, it is not electrically conductive. I came across a video on YouTube where a guy made a cylinder head out of JB Weld, and it did not ground the spark plug.
💬 FAQ of JB Weld
Q: I’m trying to block a crack between cylinders 5 and 7 against the head with JB Weld. The narrowest point between the cylinders is sleeved. Do you think it will hold up without breaking from the high temperature?
A: I was looking into the temperature ratings of different epoxy products, and I actually found one that can withstand temperatures of up to 2100F, but it has low tensile strength. I would suggest staying away from welding since the crack is 5/8″ long and sleeved at each end. Currently, I am pressure testing the area and the water jacket has held 30 lbs for 12 hours. If it continues to hold pressure, I may also consider using some high-tech block sealers. I appreciate your input and wish me luck in putting life back into this old hemi.
Q: Can I use JB Weld to repair small punctures and leaks in an older aluminum boat?
A: This is a general-purpose epoxy that worked great for me on cast iron. It says that you can use it for marine purposes, but you might also consider using a boatlife life caulk or specific product made by JB-Weld that is designed for water.
Q: Can JB Weld be used to stop an exhaust leak at the point where a donut goes flanges off of the manifold? Or which JB Weld would work?
A: If your donut is bad, I recommend that you replace it. JB Weld is a metal epoxy, and if you apply it, you’ll end up creating a permanent bond wherever you’ve applied it, making 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 or a fiberglass-style patch. Let it cure and it should be good. I have patched some long cracks that way. I hope that helps!
Q: Is there a way to remove the hardened JB Weld or soften it once it has hardened?
A: You could try using 747 adhesive remover. It dissolves many types of hardened epoxies, and one of the reviewers in those listings specifically said it worked on JB Weld. However, please note that (1) you need to soak your item, you can’t just brush Attack on it, so this will only work for small items; (2) make sure Attack won’t dissolve your parts; and (3) be sure to read the comments and safety instructions and pay attention — this is seriously toxic stuff.
