I tried bending 1/8" diamond plate, not fun at all.
I went with rhino line for durability and easy touch up. Powder coat is nice, but something that big and custom was gonna cost $$$. Plus it is hard to touch up. With rhino, it is vinyl, super heavy duty, 30 bucks a quart, and that did 3-4 coats on the whole package. That makes it super easy for touch up. I was considering rhino lining the cladding, but I gotta wait and see how bad sun fading is. Maybe after xmas if it still looks alright.
