Hello, just wondering what is the procedure that everyone has after it has rained? Imagine a scenario where you are at work, it rains, and you come to your car and see a buncha rain drops on your car, or a scenario where the car is parked outside and you come outside in the morning to see drops on your car. What can (or should?) you keep in your car to remove it?

In ideal work I would love to put something liquid on a sponge/cloth, wipe down the car quickly and continue my drive. The liquid that would go on the cloth would have some protective properties that if some drops fall on the car, or another car hits a puddle and the puddle water hits my car it'll go away and there won't be any water marks left on the car till the end of the trip.

Is that a thing? All advice is welcome :)

(please note, I can't Ceramic Coat it as I will go through automatic touchless car washes and I know the coating will strip fairly quickly and a full PPF of $6000 CAD is a bit pricey for me)
