I'm kind of a cleaning freak and I find myself always wiping down and blowing the dust off my STi. Well, it looks like I did more harm than good. I looked at the purplish antenna lens cover and it looks like it now has swirl mark scratches from me always wiping it with my t-shirt. Will this have an effect of the range? Can this be fixed if I buff it out myself? Do they sell that purplish lens cover separately? What do you guys recommend?
