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.

I used this to bond aluminum box channel for solar panels to a fiberglass RV roof. I was careful with prep and very happy with the results. 1000 miles later, no issue. I plan on installing an additional channel to create a safety cables back, just in case, but this stuff bonds great. I used it without the tip, it is thick, but easy enough to use. Watch the expiration date!

I did not notice when I received the product. Now, a month later, I discover there is no nozzle in the bag when I opened it.It appears this a common problem with this product.I will have to kludge up my nozzle. The adhesive better work.

Fantastic adhesive. We use this to hold down solar panel brackets then Infinitape over that. This has got to be the most sticky thing I’ve ever used. Make sure you only get it on what you’re trying to glue. L O L.

This product was recommended by the manufacturer of a solar panel that I purchased. Worked great, but it was a hassle to get it to follow through the nozzle. The stuff was to strong it broke my caulk gun.

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

It was so stiff that my caulking gunhandle bent when I tried squezing. I cut the tube open and used a putty knife to spread it onto the brackets for my rv awning.

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.
