Hey Nick, so far so good with the rain, altho I wasnt driving the truck it was sitting outside in the rain. I applied it 2x and the second time with a soaking coat, I let it dry for about 3 hrs then wiped off any excess. It does nothing on rubber like the bottle says. On all hard plastics still looks great, I did find it likes some plastics over others. Stay tuned Im hoping "The Count" is a man of his word
