I had posted earlier that once it had stopped raining, the paint on my brand new car looked horrible. There were water spots etched into the paint and a lot of rail dust. I clayed the car yesterday and it removed most of it. The are still some spots around the edges of the panels I need to work on. Once I get it all cleaned up, what should I use on the paint? Some sort of sealer? Wax? I get a lot of fine droplets of sap from the trees in my neighborhood plus the stupid birds. I would like to put something on it that protects it from etching again. I'm new to detailing so a little clueless.
