Bill,, Just my opinion. Polished is easier to maintain than sanded. Bad news when you get a minor rock hit. Polish means pecking it out, file, sand, polish. Paint, well you know the process. I think most people would think they were looking at painted fiberglass. With polished they think it's chrome or stainless steel. You tell them it's polished aluminum, so they rapp their knockles on it. True. Either way, we need to go on a run somewhere when the weather is right......Ron.................................... .............................................
