Truly amazing formula, firstly it doesn't smell like silicone/it doesn't smell at all...it can be cleaned with alcohol if it gets dirty, it doesn't dry in the tube even after a year, nor in the nozzle, it sticks like a suction cup/rock instantly, can hold very heavy objects, dries in 10 minutes and fully cures in 6-7 hours, becoming extremely hard and elastic...it deserves not a 5/5 but a 15/5 rating....I won't change it now for anything else, it sticks to all materials: metal with glass, wall with plastic, wood with stone, wood with wood, and it is the best adhesive for sealing between joints with large expansions and contractions, tested during the winter period in a wooden construction between the joints, we are talking about crazy adhesion and incredible strength. Also, I should mention that it doesn't react to external conditions such as cold, heat, humidity, UVC radiation, sunlight, and the company Bisson offers a 25-year warranty...what else could you ask for from a construction adhesive...it doesn't smell at all, it's like water, it's hard yet elastic, crystal clear transparency and perfect bonding, it doesn't dry inside the tube nor in the nozzle, and it can be cleaned without leaving any traces with alcohol...oh...I almost forgot to mention that my shopping for years now consists of all construction materials, especially adhesives...I rank this one at the top for the aforementioned unbeatable reasons...end of warranty!! You will remember me!!! It is also available in white, brown, black, and transparent colors!!!! It can withstand a huge load like a suction cup, very hard and elastic, stronger than windshield adhesive...also, I should mention that it doesn't tear and you can even make elastic molds with it. I tested it on a gas tank and it didn't even react to gasoline...I will make a mold to see and come back...until then, remember with closed eyes, it is TOP
