Came in clutch for a failed print
Size: 2 oz
Had a very large, multi-day 3d print fail on me. I was able to print the missing portion but needed to bond the two areas together. because of the large area I needed something with decent working time that would hold over a surprisingly small actual contact area. This was exactly what I needed. so pros: 1) allowed me to fill in the infill at the contact area to create more surface area for the bond. 2) easy to work with after i got a method down (I recommend a test round on something if it's your first time using it before moving onto your project so you get a feel for it) 3) shapeable both during application and after to help smooth out the shame of your failures 4) surprisingly strong. I needed the bond to hold about a kilo of weight, and after some testing that appears to be more than easy for this. 5) probably the longest working time out of the alternatives for what I was trying to do. (i.e. CA glue, plastic cement... etc) Cons: 1) just a touch less working time then I would have hoped for. it said 25 minutes, but started to get hard to work with around 15 minutes. Again, WAY more than my other options, but it did lead to extra post processing work I would have liked to avoid. 2) it's a touch harder once cured than the plastic around it, so when sanding it I was tending to take away more of the base material than than the epoxy, but i sort of expected this going into it. Until I find a better option for this specific use case, this will remain my top choice.

Small tube that helped my chair
Size: 2 oz
I got this PlasticWeld after my daughter suggested it for the cracked plastic arm on my old desk chair. I mixed the putty and pressed it into the crack, then sat reading the paper while it hardened. The repair feels strong, but the color looks a bit off and slightly lumpy, so it’s not exactly pretty.

handy fix for trail gear
Size: 2 oz
Weekend hikes have taught me to fix small gear problems before they turn into trailhead hassles. I bought this putty after the plastic latch on my gear tote cracked. One Saturday, at the trailhead parking lot, I kneaded a bit together and pressed it over the split before loading my boots and snacks. It shaped easily, and the latch stayed together through the hike and the ride home. That was handy. The putty felt tacky on my fingers, though, and I had to wipe them down before grabbing the steering wheel. I also wish the little amount I mixed were easier to judge for such a small crack. Still, my tote closes again.

Fixed my cracked shower caddy
Size: 2 oz
I grabbed this for my dorm shower caddy that split right before midterms. I kneaded the putty for a bit and pressed it into the crack, then propped it with a shampoo bottle while it set. It’s held up fine to daily showers. Only thing, it smells a little strong while mixing.

JB has come a loooong way since the 1990's
Size: 2 oz
I have to admit, I was pretty wary about trying this, which I used to patch a hole in the wall of a Litter Robot globe. I was first introduced to "JB Weld" in the 90s, and back in those days what you ended up with was a bond that looked like metal, but would easily crumble just by applying pressure with your fingers. THIS STUFF, surprisingly, dried much harder and created a very tight, high quality bond with the plastic globe of the Litter Robot. I experienced none of the difficulties with this that I experienced back with JB Weld in the 90s. It was not runny until dry, it stayed in place, dried and bonded like a boss, and it looks pretty good, considering I haven't yet sanded it. All in all, this product delivered on its promise, my LR3 globe is once again fully functional, and makes me completely satisfied. There is a bit of a smell when the product is fresh from the packaging, but nothing that I could sense once dried. As for the people who have posted saying it doesn't dry, it doesn't work, etc... I have to wonder if they followed the instructions and actually worked the product to mix it as the instructions indicate, because for me, drying was NOT an issue. In fact, I would almost have to argue that it dried a little too quickly. Also, wear gloves when using this product. If it gets on your fingers and dries, it's difficult to clean off. The instructions say to wear gloves, but I'm impatient.

its sticky messy and hard to work with with but it works
Size: 2 oz
I'm this to seal gaps on a 3D print. Material is PLA so adhesion isn't an issue and I can paint over it just fine. I haven't had to worry about chipping as I sand to down pretty good. Thats about all the good things I have to say about this product. My major gripes are it's sticky, messy, and hard to work with. You can't wear gloves when working with this because it sticks to the gloves. It's messy because it sticks to your hands (and gloves) and leaves a white residue on both your hands and the surface I'm working on which makes clean and precise application impossible. Because it's so sticky you can't get just the right amount for what you need either. It dries out fairly fast so you can't sit there and play with it because it's sticky so you have to work fast. After the product dries it dries very well. So well in fact it makes post processing 3D prints an actual headache if you used too much putty. It's almost impossible to not use too much putty because it's so sticky, dries so fast, and is in general hard to work. Have I mentioned how sticky this product is yet? Like I said it does the job but I would not recommend using this for smaller gaps or dips you need to patch. This is better saved for bigger jobs.
