I purchased my black srt-6 2 weeks ago with only 450 miles on it. There are water spots stained on the car around all the curves and crevices that typically spot. It looks like someone washed it with really hard water or maybe these are calcium deposits. I have washed it twice so far and they do NOT scrub off. You can even scratch the spots with your fingernail and it does nothing. It looks like they are baked on, like the car sat with these spots in a showroom for a year....which it might well have

I just purchased a Meguires clay bar and wax. I was hoping someone might have some ideas. And should i attemp to clean the spots off before clay bar and wax, or will these 2 procedures remove the spots?
