good product
my husband said that this really works for plastic, easy to use and has held together anything he has glued.

Satisfied with the product!
All products in the image arrived - the bottle contained the cap for the needle, and the bag had the applicator tip. The container was full, with a metal cap inside to seal it and prevent leakage. Unfortunately, upon breaching the seal the cap ejected itself with some force and spilled a bit of cement on my desk, liquefying the paint on my desk. I am fortunate to not be blinded, I suppose. The paint has dried now, so all is well. Regardless, upon testing the product, it works exactly as I intended for bonding PETG 3D printed parts to Acrylic. I am satisfied. I suggest letting the cement come out of the bottle on its own, there is no need to squeeze it.

Quick cure time
This product works as advertised but the surface tension is higher then water so went everyplace except the squeeze bottle so the extra that got on the acrylic stained it and couldn't be repaired. I used a glue needle and it worked way better. I also used painters tape to keep the material where I wanted it. It cured up nicely.

This is what you want for acrylic!
Great product, hasn’t changed in 40 years. There are reviews about the product dripping out of the bottle while tipping/using. *The trick is to pre-squeeze the bottle causing a negative pressure when tipping so nothing “drops” out. **works every time! Product flows well and flawlessly joins parts/panels/etc..

Not even worth the effort it took to research.
I have used many different types of bonding agents. Everything from the cheapest pack you can buy at the dollar store all the way to the most expensive I could purchase like locktight, and gorilla glue. I typically like to find products that are specific for the project I'm working with. In this case it was plexiglass, or acrylic. This product was described as fast acting and strong and for a reasonable price. Or so I thought. It comes in a metal can which in its self is horrible to work with. There is a piece of metal that you have to remove in order to even open the can. Hopefully in doing so you don't damage the threads for the cap. It comes with a small bottle and a needle like tip/applicator and that would be fine if the liquid wasn't so thin that when applied to the material it basically runs all over it. Not good if you're looking for a finished looking project that doesn't require additional work in order to do so. Not to mention you will waste quite a bit just trying to pour the liquid from the can to the bottle. In my opinion you would be better off sticking with gorilla glue or locktight rather than this stuff. All puns intended.

Great Product but be aware of gas buildup in the can
This product works well. It's extremely thin and evaporates quickly. It was difficult to unscrew the cap from the can but once this was done there is a snap-in insert in the opening that needs to be pried open. When I did this for the first time, the insert went airborne. I used the product and it worked. When I went to use it a second time, the insert popped again but not as high. Just be aware of this when you use it. It also dissipates very quickly. You must be fast when using the product. I used a brush to apply it to the acrylic that I was gluing. It evaporates instantly so I had to re-load the brush multiple times to get enough of the product onto my project. FYI.

mIssing applicator
I have used this product many times, and it works great—you just have to work quickly. Unfortunately, I have encountered some issues when ordering. One time, it arrived in a padded bag, got squished in the mail, and leaked. I don't think that was the seller's fault, though. My most recent order arrived today, but it was missing the applicator. Amazon informed me that they couldn't replace just the missing piece, so now I have to order applicators separately to use it. I still give the product 5 stars, but whoever handles the packaging deserves only 1 star or less.
