My cobra is the Oxford white and the owner before me had it outside for 2 months because he moved to a condo with out a garage and there are some water stains on the paint anyone know of a good way to get these out I washed it and waxed it and they don't come out but I hit it hard with a major eraser in one spot and it came out but I don't know if that will mess up my clear coat what to do !

I used a acid wash product from a local detailing shop.http://www.knipps.com/wp-content/uploads/2012/09/107spotnotsmall.jpg When using on paint you apply it on small area and then rinse off. Like half of the hood, etc. When done you can rub it out, clay bar, etc. and then wax. I tried everything and it was the only thing that would remove the water spots. Also works on glass.
The only other option would be to have it professionally wet sanded and polished.
