AP Products 017-90916 Sikaflex-252, Black

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.

My tube of sikaflex 252 came just like everyone else’s. EXPIRED, NO CAP/CONE, and so hard it would not come out of the tube and bent my caulking gun handle.

I had some damage due to a bad tow after a broken ball joint, and I needed to reglue this. I talked to my RV manufacturer and they said this is what they use, so it's what I got. I wish it came in a smaller tube or had a cap that made it possible to reuse, but I knew this was probably a one-shot use, so I'm not knocking any stars off for that. It goes on very thick and sticky, and seems like it is going to do a very good job.

The applicator tip was not included and the end was very bent up. I'll still be able to use it but it would have been nice to have it arrive in better shape with the tip.

Did the trick

Love using this stuff, but got some reason. This batch came through with a large tip rather than the more typical tip.. see photo

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

They seem to send out the oldest product they have. Mine was set to expire two weeks from the time I received it. It was also so hard to squeeze out of the tube that it broke my caulking gun, and that was after warming it up to get it to flow a little better.
