Well my car seems to attract blemishes more than any other silver car. Last week I noticed that I had some water marks on the hood and trunk. But I've never seen anything like this before. They were white in color, and when you went over them with some water and towel, it would disappear, but the edge lines would still remain. I figured they would disappear by the time I washed my car yesterday, but under lighting, I still noticed the outlines of the water marks. The only thing I can think of is that this could be from the sprinkler system water (it hasn't rained here for a week and a half). I'm trying to decide what to do next, but I've never used any hard cleaning products. Suggestions?:dunno:
