I thought JB weld came in two parts?

It did last time I used it...


This pot metal handle, are you just going to sand it and paint it or what?

JB Weld website, products section, click on each product for the information you are seeking... that was so hard to find, let me tell you.

Now, what brand and make of two part epoxy do you wish to compare it to, so that we can do the rest of your homework for you as well?

Opps I have never used JB Weld so I did not know it comes in two parts. If it comes in two parts I guess it is just regular old epoxy. So why is it so magic.

I know it has metal powder in it; probably iron. Not sure how that helps adhesion or strength. I found this out by trying to JB weld a very strong magnet down, the magnet pulled the JB weld onto itself.

JB may not be a magic final answer [I haven't found one yet] but it sure has bailed me out on a lot of projects in the past. Good stuff, I keep both the regular and quick set on hand all the time.

JB Weld IS a two part epoxy. This is a bit like comparing Budweiser to beer.
There are many variations in the formulation of epoxy adhesives, JB sells two of them.

JB Weld comes in a 2-part syringe applicator and dispenses equal amount of the adhesive and catalyst. Good shit indeed, great for metal, plastic, etc. Can be ground, sanded to a point and painted over.

Some of you guys are truly funny.

JB Weld (as has been said) IS a two part "epoxy".

It comes in at least two forms (that I know of).
1. Old fashioned squeeze tubes. That has a slow cure time (about 12 hours I think).
2. Syringe type tubes, a double stack, that when you press the top, equal (sorta) amounts are brought forth. This is the 5 minute cure veriety.

I prefer the original squeeze tube style for most of my work. From slot car bodys to motorcycle to full size car repair.

If the parent material is properly roughened and cleaned, the JB Weld is tough stuff to defeat. It even seals against gas leakage.

Yup, JB good. Just prep the surfaces properly, I've used it in some heavy industrial applications with good results.

I agree that JB weld is good for some repairs, but something that will be used as much as a door handle might be better if you sent it off to Chrome Plater Josh and let him actually "weld" it. Not sure how he does it, but he fixes a lot of that stuff prior to plating, and has some really good feedback on here. Sounds like he is pretty reasonable on price too...

What to do with the door handle kind of depends on how it's broken. If you post some pictures of it we could probably predict whether or not epoxy (such as JB Weld) will hold, or if it'll break again.

If it's a small area that has a lot of stress on it, then it might not do the job. The tensile strength of epoxy is much lower than the strength of metal.

I've had success backing up the joint with a piece of shim stock, a good idea if you have the room on the flip side. Just rough up all the bonding surfaces and clean them up with carb cleaner or lacquer thinner first.

Like previous posters have said, JB Weld IS a two part epoxy.

Some of the best, most chemical resistant and durable laboratory countertops I have ever worked with have been made of very similar epoxies.

I don't use it on anything safety or structural on my hotrods but it's great for most anything else.
