This did take a few hours to set up properly and I wouldn't touch it for at least 24 hours but we use this to connect our L brackets from solar panels to the roof of our fiberglass travel trailer and this worked like a charm, far better than VHB on the same surface. 10/10!

Used this to install solar panels on my van roof 3 years ago. Panels are still holding strong after being in the snow and extreme heat of Arizona. Stands up to using a power washer to blast debris from the channels under the panels too. No sign of degradation. Got another tube to install a new panel and was pleasantly surprised to get a metal tube! I did have issues with the plastic tube bursting during application cuz this adhesive is very thick

The product arrived without the nozzle, which is impossible to find anywhere since the cartridge does not follow a standard size. The tube was completely dented and came inside a dirty bag. Honestly, I’m not surprised this product has such bad reviews.

Worked great on solar panel install on my TPO RV roof. I did make sure the surface was properly cleaned, prepped and 3 days of curing at 60-80 degree F temps before hitting the road with my RV. Put 1700 miles on them at interstate highway speeds in windy conditions and so far, so good! The stuff is thick so a good heavy duty caulk gun is recommended. Another caution is have your work prepared properly. I found out the hard way that once i started the tube, even though put a nail in the end and taped it up, it still set up in the tube so i had to start a new tube. Plan you work properly because it is pricey.

Used to mount solar panels on camper roof. Holds as good as a screw would but no need for additional holes in the roof!

I use this to glue flexible solar panels to RV roofs. Knowing that the product is somewhat hard to extrude and having multiple panels to glue, I've used powered caulk gun. Unfortunately, the tube contents were very hard likely because being close to expiry (less than month left) or improper storage... The tube leaked lot more of its contents into my caulk gun rail and gears than to actual surface I was applying it to, basically ruining my new caulk gun. That being said, unlike with other products (that have completely detached during a rainstorm) the solar panels have withstood two Arizona summers, lots of rain without any sign of detaching.

This product was recommended as an adhesive to attach c-channel to the side of a conversion van to allow for the installation of an awning and it has done the trick perfectly. I warmed the product slightly in the oven (preheated and then turned it off) to make it flow from the tube easier and used painters tape to tape off the area were I did not want the adhesive to go. After I applied the adhesive I followed up with sheet metal screws to keep it all in place. I used a cloth sprayed with brake cleaner to do the final wipe off clean up and the end result looked professional. I've used the c-channel numerous times, even in strong winds and it held fast. I would recommend this product. I know it is a bit pricey but in this case, you do get what you pay for.

Both tubes arrived without the application tips. Shipping was right on time and its exactly what I ordered. But I cant use the tubes without tips for what I'm doing. Both tubes were wrapped up in plastic bags, so clearly nobody noticed they where missing before that.

Easy to apply, fast setting

Excellent product but it’s very stiff and you will need a heavy duty gun to apply quickly.

Great for bodyshops. Much cheaper than we were paying

I received an expired tube.

the seams on the trailer were separated and this worked at keeping the water out
