I have 68 miles on my Ace. I have been riding it on woodland trails that have some red clay wet spots. I have accumulated a lot of red clay on the Ace. This morning I noticed a red arc about 4 inches long on each front fender immediately below where the door nets snap to the ROPS. The door netting straps have about 8-10 inches extra straps that flop around in the wind. They were soiled with red clay and had actually worn a rough arc in the plastic fenders. I think I can polish it out with Novus Plastic Scratch Remover. I have secured the end of the straps so that they cannot flap against the fender.
