@aaron.... what kind of outdoor life do you experience with the 8624? We've installed a couple times indoors... but i am unsure of its durability outdoors in a freeze /thaw climate...i've pitch to a couple clients, but am always unsure what to tell them as far as longevity? BTW..we installed it on 75' of polished cinderblock... was up for almost two years with minimal signs of lift.......... until Sandy came and flooded 4' high of it.... it actually stuck pretty well... but with all the salt water, chemicals , and environmental cleaners= FAIL.... heres some before pics...
