North Texas has extreme temperature and humidity variations. After reading the reviews I figured it would fit. We used it on a commercial project that used composite decking panels as siding. When I went there to check it out within a few days, about 1/3 of the caps had partially popped out. The first picture shows what happens after a few days of healing. I'm sure this gorilla glue will work in many cases but not in mine. I probably should have used epoxy instead. Now it costs me a lot more money because I have to hire workers again, have to rent an elevator again. A headache and lesson in buying something you've never used online.
