Perhaps, it is gonna be a off topic! Rain is very very usual where I live! Thus, I used ceramic coating for my car! As rains are heavy here, I was looking for something that can help me to see what is coming from front without any difficulty and came across the nevert rain repellent (I found it here)! Does anyone has any experience with this?

 

Sounds like rain-x. Never used rust-oleum on my car.
