When i said "rainfall", i mean rain storm. I wonder if the extremely heavy rain had an effect on how the water set on the paint. Because later on the day after the car had been parked for a while in light drizzling, the beads were almost perfect circles.
When you use the mist settings on the hose, you get extremely small beads. When you use the jet setting, there's all different types of beads. When you use just the hose to flood, the water sheets right off. I wonder if the different pressure causes a different effect?
