My neighbor watered my car a few weeks ago, and naturally it left spots. The spots looked nasty, I was pretty sure he watered his yard with a sandblaster. Anyway, I did the obvious thing and washed it later that day. Well, a lot of the spots came off, but it still had the outline of a few on the hood. Similar to swirls, they aren't noticeable unless you look hard, but I see them. Again though, I figured they'd come off soon. Well, yesterday I clayed and waxed the whole thing. Still has spots!!!

Anybody ever had this problem before? If they didn't come off with the clay I don't know what will do it. Does anyone here know a good trick to get them off? I'm sure if I polished it with some ultimate compound it would come off, but that just seems like a lot of work for water spots.

Any ideas?

And no, I don't park close to his yard anymore.
