Sikaflex-221 Multi-Purpose Polyurethane Sealant/Adhesive, 10.1 fl oz, Black – Permanent Elastic Seal, Sandable & Paintable, Non-Corrosive, Bonds to Metal, Plastics & More

I used Sikaflex to adhere a roof wing to the back windshield of my car, and I’m seriously impressed with how well it worked. The bond is incredibly strong and feels permanent once cured. I let it set for about 24 hours before driving, and even after months of highway speeds and temperature changes, the wing hasn’t budged at all.The application was pretty straightforward, it has a thick, tacky consistency that gives you enough working time to position everything correctly before it starts to set. I’d recommend taping or clamping the part in place while it cures, because it does take a while to fully harden. Once cured, it’s flexible enough to handle vibration and movement, which is great for automotive use.One thing to note: this stuff is messy. It’s sticky, and once it gets on your hands or paint, it’s not easy to remove. Wear gloves, mask off surrounding areas, and have some cleaner or mineral spirits ready.Overall, Sikaflex delivered exactly what I needed, a strong, weatherproof, and vibration resistant bond that’s holding my roof wing securely in place. It’s not the cheapest adhesive, but it’s worth it for the strength and reliability.

Used to re-adhere the back sliding window assembly on my2015 F150. If you have the truck you know the inevitable issue where they pop off. Simply cleaned off any old adhesive and applied this and taped into position. Has been holding great ever since!

If your bumper is falling off of your car, this is the right stuff to use. Get it hooked back in place. Put this adhesive on and you will not have to worry about it coming off again

really good adhesive/sealant. I have used several other cheaper amazon brands and it lays significantly smoother and like a thick cake frosting consistency - it also hardens and connects with much stronger bond. Highly recommend using this and paying the price over the cheaper stuff out there

Normally a great product, but is no good past expiration. I returned this tube because it was too set up to work with.

My kitchen sink fell in, I tried to glue it with some other products but it did not stay. I tried this after it was recommended by AI, and it's been fantastic. After you apply it, brace your sink underneath with some temp straps and / or a 2x4. It's been 6 months of heavy use and holding up without an issue so I think it's good to go.

This sealant/adhesive works great and performs exactly as expected. Good quality, easy to use, and I would definitely purchase it again.

I am using this to adhere wood and foam insulation board to metal. Works very well for both!
