I would clay bar it, mainly because that will fill up and file down most imperfections on the surface. I can't say that this will eliminate the water spots entirely, but the paint in general will look alot better. I have crappy sprinklers in My apt. complex and not a single dry car in the lot every morning, so I get new spots daily. I'll just repaint when I move...
I know nothing about acid washing cars, so I can't rightly comment on that. Maybe someone else will know.
