Hi. I need to update my trailer for next year. I bought it new in 1994 and no matter how much I tried to prevent it from happening the entire trailer except the side door has turned to "chalk". Obviously, the door was made with better material. It is, or was, a bright Red and is now a dull pink! Question is, has anyone ever just torn off the aluminum panels and replaced them with new? I would want to go with bright Red again. What is the best material to buy and from whom? Any idea on price doing the labor myself? Any help is appreciated. Thanks, Jay
