today when I got home from school, I decided to wipe off some dirt on my car and opened the hood to see that there was something wrong... there was a huge splatter of what looked like dirt water on the passenger side of my engine bay. I've felt no awkwardness while driving today or any other days, and thought it was from a bad wheather we had few days ago but it bothered me since it was only on one side. Does anyone know or can give me an idea what happened? Thanks

 

high velocity splatter patterns look liek they were made with a paint or primer applicator.
