If you want to replace the bolts or rivets or something and just use this, it'll do the job. I know there's a lot of people that complain about it being past expiration date. If it's past the expiration date just send it back. Don't give it a bad review. Understand this stuff is extremely thick. A little on the hard side. But if you take these tubes and put them in the oven for 5 10 minutes and get it hot. You can put it in any caulk on and easily squeeze it out. But this is not an adhesive that you use a little bit and then seal it up. To use in a couple days later. But this stuff is amazing. I build composite square drop trailers and I don't use bolts or screws or rivets. This stuff is indestructible. I have never had a problem with anything or any seam coming apart. I'm not saying everything is going to be the same but what a overland square drop trailer goes through. Driving down rough roads in the middle of the desert for hours. And holds up. This stuff is amazing. I use it on composite panels and you can't really screw a hard panel. It doesn't work. So you got to rely on adhesive? I've been using these adhesives for a few years now and I've built 22 trailers with this stuff. Normally I buy it in bulk I needed it. My shipment was a few days out. So just put it in the oven and you won't have any problems. Maybe for like 5 to 10 minutes. . It will easily bond to wood metal fiberglass aluminum. Foam without any issues. Amazing product if used right.

The item had no nozzle and therefore no way to dispense the product. The inner seal was also broken and the item was repacked in a sealed clear plastic bag, clearly defective and returned. Look at the other reviews very similar.

As expected, great product, adheres well, and lays smoothly.

As far as an assembly adhesive this stuff is amazing so far. But only buy what you need. This stuff has a very short shelf life. I bought an extra tube for a project a year back and it hardened in the unopened tube within the year.

The product does not come with the tip shown in the picture/description. I will have to buy a separate tip if I can find one. Will not work with the tip that came with it for what I need to do. The tip that comes with it is 1/2” wide v notch.

This stuff definitely works well as it should. I used it in my campervan build to attach wood to metal. The only downside is that they sent me an expired and dented can so it was extremely difficult to dispense, even using two hands. Avoid breathing it in or getting it on your hands, very toxic!

Next to welding two panels together , this is next best thing. Used it to install custom made rocker panels over the rotten ones on my lincoln. Was a cheap and easy fix. Appears to be high quality product. Quite pleased with results

Ordered March 31st, 2025 to mount a bike rack to my van, but it wasn't warm and dry enough outside to use it yet. Just went to use it today, and found it had expired May *2024* and the tube was unusably hard. I'm outside the return window, so I was scammed out of $20 because I delayed installing the bike rack. Anyway, check the tube's expiration date after you order, especially if you don't intend to use it right away.
