Excellent Sealant for Multiple Uses
This product is a great product for sealing leaks, bonding materials, or weatherproofing. I used it on a cracked window frame, and it held up perfectly against rain and wind. The clarity is excellent, and it doesn’t shrink after drying. Works on glass, metal, and plastic very handy to have around

VERY Strong Bond And Temperature Rasistance
बेस्ट क्वालिटी। Nexon कार के कैथेलैटिक कनवर्टर का पाइप नीचे से लगने के कारण बैंड हो गया था और एक्जॉस्ट पाइप के फ्लांज में बीच में से बीच से ऐर जाने के कारण गाड़ी बहोत ही ज्यादा आवाज करती थी कम्पनी ने उसका खर्च करीब 70000 बताया सिर्फ एक मामूली ऐर लिक का बाहर भी पुछा बड़े गैरेज जैसे की Roger Garage कोई रिपेयर नहीं कर पाया आखिर में मेने एक दिन यह ट्यूब लगा के flange वापस जोड़ दी और 1 घंटा सूखने दिया बाद में 5Km चलाके देखा आवाज बंद हफ्ते बाद लंबी 200 Km तक इंजिन गर्म करके चलाया आवाज आना अभी तक बांध है और टयूब जैसे लगाया था वैसा का वैसा ही है तापमान से उसे कोई फर्क नहीं पड़ा थैंक्स JB weld me 70000+ बचाने लिए।

The silicon inside tube was not accessible easily
It was very tough to use it. Had to press very hard for the silicon paste to come out of the tube

More useful than the readily available sealants
Full strength RTV silicone selant/adhesive with no fillers and a sharp whiff of vinegar. More useful than the readily available sealants.

Spoiled product
More than half of the tube was already in solid state.The silicone did not come out.Thats cheating .The JB tube is expensive than other brands.The company should keep a check before sending spoiled product.

Good sealant, use your own applicator.
Used this to seal up an aquarium and it worked super well. It hardened fully in about 48 hours, but I probably could've scraped off the excess after 24. It's super clear and blends into the background. The applicator didn't work very well, so I put it in a Ziploc and piped it on like frosting, which worked much better. Aquarium is watertight now.

Works great
At first i used it with the nozzle but its hard to squish it out so I had to cut it from the second circle to make the hole bigger which worked, please do not force it through the smallest hole since Ive seen some comments complaining that it bursted open and made a mess. I would recommend you remove the nozzle when you are almost done and clean it properly by passing tissue through it, using some of that product leftover. While this might be messy and a bit wasteful it will prevent both the tube and the nozzle from drying up since the nozzle doesnt have a seal. Now i use it without without nozzle and it still works nice for areas that dont require precise application or tight areas and its an amazing adhesive, it says it dries in 1h but id recommend leaving it at least half a day, do the work at night and leave it overnight maybe. Ive used it to glue some shelfs in the kitchen and put spices and sauces which can be quite heavy, left milk and other heavy items to test the durability and its been 3 weeks holding all that weight, also used the glue to seal corners in the bathroom and its completely waterproof once dry. The next time u open the tube there will be a dried up crust on the top, if u squeeze a bit it should come out, i didnt throw it away and actually placed it back once im done using the product and this actually works as a second seal that prevents another dry crust. Overall amazing product.

Does what it’s supposed to do
I was happy with this glue. It was easy to use and control. It was a great alternative to hot glue . The items I repaired stayed together well, and drying time was reasonable. I’d buy this again and I recommend it for household fixes. Everything I used it on was successfully repaired.
