UV Bonding & Welding Glue Kit UV Resin Kit with 3W UV Light Quick-Drying & Waterproof Liquid Plastic Welding Glue Household Repairs Only for Plastic, Glass, Metal 0.35oz (10ml)

This Glue is easy to use and bonds (and hardens) instantly with the supplied UV light. I had a crack develop in the roof area around the sunroof in my car. It was about 2” long, very thin, and I needed to seal the crack so water did not come into the car interior. I cleaned the area with alcohol, squeezed the glue into the crack and then cured it with the UV light. I was able to use a razor blade to scrape off the excess glue after it hardened. You can barely see the crack now. This product is supposed to be waterproof after it is cured and it did exactly the job I was hoping it would do. The cost to fix this at a body shop was $1,500 in order to replace the roof panel. I think this is a great product that I would highly recommend!

The light I don't even think works for the glue bought with. It dried with blowing on it and not the light. It had no effect. The glue is not even sticking to anything but paper.

I had an older iPhone with a moderately broken screen. It wasn't worth the cost to repair, but It still worked fine. I applied this product on the screen and then floated a glass screen protector on it. I exposed It to sunlight and poof! The adhesive was cured. It had filled in the cracks making them nearly invisible and the surface was smooth and firm to the touch. One drawback was I let some of the adhesive get into the speaker opening which make it difficult to hear, but it's fine with Bluetooth headphones. I'm still using it as a dashcam. Awesome stuff!

I used this to glue my brother glass figure back together and it works wonders it dries quickly and the smell isn’t bad but it gives very high quality and good value for your money.

It smells like the popular instant glue, but it is thick. It dries, or cures, clear. It is not very hard, but it is somewhat flexible. Cure time is quick. This holds well on plastic. It is useful with a nice bead can be applied on the outside of the joint. I use it to secure groups of very tiny electronic wires and keep them organized. It can be peeled off or scraped. It does not find its way into a joint or fine spaces like the regular instant glue. It would be nice if it were stronger, but it's pretty strong for most things. Basically, if you wish to do a glue fillet (like a weld on the outside or on a corner), this stuff is very nice. It tolerates significant gaps between pieces, so it is a nice way to hold irregular parts in place, or hold parts until another bond from a different glue cures internally. It DOES stick to PLA and circuit boards, which makes it very handy for a sort of strain relief or to keep things from vibrating. In many ways, it is similar to hot glue, but more clear, stronger, harder and less viscous. If a PLA part has to be joined for full material strength in a butt or lap joint use some kind of solvent instead - this adhesive is nowhere near as strong as PLA. The bottle has quite a bit of juice in it for the money. I will probably use it all up before learning about what it works best on.

This glue and this ultraviolet light. They are perfect. I love them, they're very good.

1st of all it works. BUT o ly if you use a stronger black light. Fortunately I had one on hand. The one they send is crap. Its basically a flashlight. On the other hand, the glue works as described. Its acrylic. And only dries when exposed to UV light. Its best to use on clear areas for best adhesion. But I did get it to work on darker surfaces. Maybe I should give them 4 stars.

Don't not hold at all
