Customer is tired of replacing his 10x10 pans every hurricane season. He had somebody put exterior spotlights on his sign and would like some form of metal panels. I don't know of any distributors (at least not in or near Florida) that sell any sheet of aluminum or ACM that large. Any suggestions? I just read an old thread on this forum about butt seaming with lord and a 2-3" alum strip. Is this the way to go? If so anybody have insight? Never used this method? I assume bevel the edges with a router or table saw, fill the seam with LORD?
