Review: BUYER BEWARE!!! - ZERO STARS!!!!! READ THIS WARNING!!! We ordered this specific exact "aluminum gray" product after research to determine this is exactly what we needed. We provided it to our workers to seal an entire 3000 sq foot interfaces between aluminum windows and wood. The product went on black. The workers asked us, we checked the internet, and it said it would cure much lighter and gray in 5-7 days. So we gave them the go ahead to use it. A week later its all still black. AND we opened another tube of EXACT SAME PRODUCT and it was actually gray out of the tube, and even worse, a completely different consistency. SO NOW WHAT???? WHAT IS ON OUR HOUSE? AND ITS THE WRONG COLOR!!!!!! WE HAVE TO RIP THIS OFF THE HOUSE, 2 LEVELS, AND REDO IT. THIS IS NOT ACCEPTABLE. SERIOUSLY. DO NOT TRUST THIS COMPANY to put in the tubes what it says are in the tubes!!
